8/3 Solaris question. How come after catting .cshrc, the atime doesn't change? Something in NFS? I dont see any obvious NFS option to control this. The file is on a netapp. \_ is noatime set? it's an NFS option that prevents that. \_ It doesnt appear to be set in the automouter map. Can it be set on the netapp itself? \_ Yes, there is a per volume option called no_atime_update that can be set on the filer itself. This is mainly for people who are really pounding the volume who could use the extra performance boost of not updating for each access of a file. -rollee |

8/2 Is there a way I can invoke abs (absolute value) from a bash script? In general how can I use math function from shell script? \_ If you're worried about math functions, then it is time to start using a real scripting language instead of shell. \_ Agreed. But, if you're not quite ready to rewrite your script yet, it's pretty easy in bash: $((x < 0 ? -x : x)) will return the absolute value of $x.

Some of these features you can get in ksh or hack into pdksh (a la OpenBSD), but for most people its just easier to use bash. \_ tcsh completes filenames with spaces. i don't know nething about unicode but it's mentioned in the man page. fuck bash. \_ Yes but tcsh uses the crappy csh scripting style. Some of us do use the while/do/done for/do/done, if/fi &c. syntax on the cli. \_ Use the right tool for the job! You use tcsh for CLI and perl for scripting.

FreeBSD boxes: rsync back and forth between boxes. -John \_ I have multiple matched drives. Every three months or so, I copy everything from one drive to another and then start using the new copy. The next time, I swap the drives. Once a month I burn stuff to a cd/dvd. Important stuff I keep in cvs. I backup my repository every other week. I'm mostly using MacOS X, FreeBSD and OpenBSD, I don't bother backing up my WinXP box, nothing important on it except DVDDecrypter :-) \_ I've read that if you let drives spin down for too long there is a good chance they won't spin up again, thus cold disk is not a good backup medium. I've done a little of what you're doing but not enough to say if what I read is true or not. YMMV. \_ From what I've seen this is only the case if you let your drives sit for years not months. Even then, most drives will work (I just powered on a scsi drive that I last used in 1997 and got some data from it last week). Also, I tried to make sure that my drives are never more than 24 months old. Around 18 months or so I upgrade to a larger pair and sell the older pair to offset the cost. |

7/1 Using sed, how do I do the following? I want to replace the first line containing a particular pattern with the 2nd line containing said pattern. For example, if "line" is the pattern, then I want this is the 1st line this is the 2nd this is the 3rd this is the 4th line to become this is the 4th line this is the 2nd this is the 3rd this is the 1st line (Actually, I don't care if this line shows up like this or gets deleted.) \_ stupid to do this in sed. use perl. \_ OK, how do I do this in perl? \_ while ( $line = <> ){ if ( $line !~ /line/ ) { $output[$count++]=$line; next; } if ( ! $firstline ) { $firstline = $line; $firstindex = $count++; } else { $output[$firstindex]=$line; $output[$count++]=$firstline; } } print foreach @output; # (Approximately) -tom \_ You don't need the "foreach" \_ Just for fun, how can this be done using sed? \_ sed is short for "stream editor". It's designed to look at the input one line at a time. making it handle line operations is unholy, and possibly illegal in most states. \_ there is nothing fun about doing this in sed. -tom \_ lots of things can be fun if you're avoiding more important work. here it is: sed -e '/line/\!bS;:M;$\!N;s/\n.*line/&/;tE;$\!bM;:E;s/^\([^\n]*\)\(\n. *\n\)\([^\n]*\)$/\3\2\1/;:S' this swaps the 2N-1'th and the 2N'th lines matching "line" for all possible N. if there is an odd number of such lines, the last one is left in place. note that the 3 "!"'s are \-escaped for tcsh; your shell might differ. naturally, s/line/foo/g to change pattern. tested on gnu sed 3.02. inserting a few newlines will make this work on soda's sed as well: sed -e '/line/\!bS\ :M\ $\!N;s/\n.*line/&/;tE\ $\!bM\ :E\ s/^\([^\n]*\)\(\n.*\n\)\([^\n]*\)$/\3\2\1/;\ :S' -alexf \_ alexf = leet sed god \_ s/leet sed god/bored new sed user/ -alexf \_ sed rules!!! \-first, i probably wouldnt do this in sed either. it may be doable in sed but your description isnt complete, so i cant suggest a solution. do you just want to *swap* 1st match of regexp with second match of regexp? finally, sed can certainly do non-line based things more easily than say grep. see e.g. the , operator. --psb \_ I want the first line that matches regexp to be replaced with the 2nd line that contains regexp.

6/29 Is there a C function to get the name of an opened file from its file pointer (FILE*)? Thanks. \_ I don't know of one. What would happen if there are multiple ways of describing the file? (Symbolic links and the like) \_ the best you can do is use fileno() to get the file descriptor number and then pass that to fstat() to get the inode and filesystem of the underlying file. To get an actual path name from there is difficult, as you could have any number of hard links pointing to the inode, and it is even possible for there to be NO links and there is in fact no file name associated with the file's inode.(i.e. it was 'deleted' after it was opened). If you *really* want to know you could run a search through the filesystem for matching inode numbers. -EricM |

6/27 Stupid UNIX question: In a shell program, how do I read in standard input? I want the program to take standard input and manipulate it in some way and then output the result to a file. Once I have the program written, I know how to invoke it, but how do I, within the program, tell it to work with the standard input? \_ Read from fd 1: while read LINE ; do echo $LINE ; done <&1 \_ If you just want to pass stdin through various external commands, it's easy; just run them, and the first one will consume stdin if it needs it; e.g.: #!/bin/sh awk '{print $2}' | sed 's/a/b/g' > file will "just work". If you want to perform actual line by line shell script programming, you'll have to do like the previous post says. But really, if you're doing actual custom programming of this type (i.e. not lots of external program invocations), you almost certainly are better off using perl or <insert favorite text munging language here> --dbushong |

6/16 It's not in any way against CSUA policy to have procmail check your quota each time it runs, is it? \_ Why would it be? \_ I think the quota file might be a bit of a chokepoint for the filesystem; probably bad if everybody were to do it. Perhaps try du -d1 instead? \_ du -d1 is way more impact than quota. -tom \_ Yeah, wow. Use your head: with quotas on every filesystem op results in a quota check; how can it be high overhead? \_ Please correct me if/where I'm wrong: quota files are maintained at the root of each file system, and, empirically, I've noticed that quota results are cached: quota -v; rm reallyBigFile; quota -v; sleep; quota -v; I imagine this cache resides at the FS root as well, so hundreds of users x hundreds of spams = 1000s of writes to the quota cache = possibly slow disk access. Different cases possible with softupdates and/or kernel-based memory cache. \_ Quotas are kept in memory, in the kernel; you can access them with the quotactl system call. There are quota files at the root of each filesystem too, but they're only used to initialize the kernel's quota information at boot time. Since it's all stored in memory, updating the quota information when you create and remove files is trivial. You only see delays because soft updates is delaying the actual writes to your files, and thus delaying the quota updates too -- on systems without soft updates, quotas update instantly. --mconst \_ you could have verified this yourself by using the "time" command to see that du -d1 takes an order of magnitude longer than quota, instead of sounding off like a moron. -tom \_ great way to encourage discussion. you rock! \_ That suggests that although writing/deleting lots of spam could load the system (which we already know) lots of people reading the quota file will probably not be a big load, or at least not any worse than reading a file of spam-filtering rules. \_ depends on your personality \_ I'll take this discussion as "No, it's not against policy". \_ you can take it that way (i would) but just be sure you don't end up a hoser; that's the policy you need to worry about here. - erikk |

5/18 Is there any Windows backup program which (1) Let's you do a full backup, (2) Monitors all filesystem changes as they occur, then (3) Does an incremental backup on only changed files? I don't want it to have to scan my entire notebook data-partition for changes; changed files should already be flagged for backup by the monitoring daemon. I don't want some hacky program that only runs file listings on specific directories every couple minutes and checks file sizes/dates; I want something which hooks into the Windows filesystem and is aware of all writes as they happen. Basically, this strategy minimizes hard drive wear, and should be faster. Thanks. \_ Um, RAID + tape? \_ Notebook hard drive. Sorry, should have been clearer. \_ You've got to be kidding. You want all this and on a laptop too? How about a 24" screen that can fit in your pocket while you're at it. \_ The "hard" step is hooking into the Windows filesystem. Apparently Sysinternals Filemon does this, but it doesn't do backup. \_ If you buy an external Maxtor drive with "One Touch", it comes with a license for Dantz Retrospective Backup. The drive+sw is <$200. \_ Does Restrospect hook into the Windows filesystem like I described? \_ Eh, screw it. I lookd up Restrospect Professional, and it lets you make a "Disaster Recovery CD", which you can boot on a hosed system and restore all the files (rather than a complete re-install of the OS and all the apps). This to me is worth more than the low-level file monitoring. FYI, the one that comes with the external hard drives is "Retrospect Express". I'll let motd know how it is in several weeks. -op \_ hell, you could just use ghost images then \_ I didn't fully explain how the feature is neat. Okay, with Ghost, you gotta do the whole freakin partition every time. Wih Retrospect, you can do incremental backups to your heart's content. Each incremental backup is fast. If your disk gets hosed, then *after* it got hosed, you can create the CD. The disk gets restored to when you last incremented. Get it? \_ You want a program that hooks deeply into windows and keeps a db of files *as they change* and then copies them to something else? I wouldn't want anything hooked that deeply into windows. Note how intrusive the anti-virus programs are. That's what you're talking about but worse. \_ That sounds like a slightly modified log-based fs. Not that evil a thing, really. I think there's a freebsd implementation floating around, yes? -- ilyas \_ Not evil per se as a concept but look at how the perform in the real world. I really wouldn't want anything hooking that deeply into a windows system if it wasn't absolutely required. \_ If it came out, I'd buy it ... if Windows were still fast. Assuming you always back up the registry, all the monitoring process is doing is collecting a list of all new/changed/deleted/moved files since the last incremental backup. The copy step occurs daily. -op \_ Put your data on a linux box and mount the samba share from windows. THen, use rsync and snapshot backups. |

5/8 On the linux ls discussion from the other day, this is my take: Using/learning linux specific flags is all fine and good, and adding new features to old tools is too, but when I have to switch between 5 different OSes in a given day, it's simply a waste of my time. There are many ways to solve a given problem. Linux's solution always seems to be "add another flag". If you're a Linux only shop, have at it. Learn all the little idiosyncracies of your favorite flavor. But god help you when you get an HPUX box thrown at you. --scotsman \_ Relax, you'll live longer. Learn how to use alias and edit the default profile. -williamc \_ You miss the point entirely. Sometimes this is not an option. If you're not a sysadmin then this discussion doesn't matter. I'm talking about efficiency in work situations. --scotsman \_ Compare: ls -S 6 keypresses ls -l|sort -n +4 18 keypresses Is that something you want to type for such a simple user task? It's just arrogant and silly to not do it, for something so common and easy. Including the date or name sort is no more valid. On soda there is "dir" which has it. Go study UI principles. \_ This is the stupidest thing I've seen on motd in weeks. Comparing the number of keypresses? Christ, man, it's about getting the job done as effectively as possible. When you're down to counting keystrokes, you've lost touch with reality about what constitutes a sane metric for efficiency. \_ effective? What's more effective about piping to sort? it's more limiting, and more obscure. And yes, it takes more effort to type that shit out. It's not about "efficiency" so much as simple ease of use and consistency. That's reality. Not some elitist ubergeek deciding to simply put a note in the man page about how it's not needed. Obviously the fact that it's in the man page means it's a desired feature. \_ What's more effective than piping it to sort? Could you have missed the point any more? Jeeesus. \_ Ever stop to consider you're the one missing the point? \_ Yes, but I'm not. Have a cookie. \_ It's not more obscure. In fact it's less obscure and more consistent unless you're immersed in Linux. Why is this point so hard to grasp? --scotsman \_ Forget the status quo, it's more obscure from a usability standpoint. I have to know about the sort command and that I have to do ls -l and sort on that 4th column but oh I might need the -n for numeric vs. lexical sorting. Honestly this is really really basic. It's not consistent that there is built-in date sort, or alphabetical sort, and not size sort, \_ In 10 years, I think there still be be Windows and Mac OS. the only other basic file property. It's not consistent that I need the long detailed listing when with a builtin it could just work like normal. And it's just plain inconvenient. You don't have to be "immersed in Linux" to see that. I barely even use Linux. It's just common sense and refusing to worship status quo. Oh and I'm just arguing about what's correct, not the "least-common-denominator" factor of working with 15 different unixes. \_ Did it ever occur to you that sometimes the status quo *is* the status quo because it has worked well since before you were born and is just plain better? \_ The extension of the point is that when you have learned to use sort appropriately you can then apply it in other cases. Read the philosophy of UNIX page partha posted below. If you don't work on 15 different unixes then, as I said above, this discussion doesn't apply to you. If I get pulled in to help out a client to save a $100k sale, I have to get the job done quickly. Knowing the least- common-denominator allows me to get up to speed quickly. It's not worshiping anything. It's doing my job well. --scotsman \_ you know, it's possible to know how to use "sort," and still support the idea of internalizing functions in Unix utilities in appropriate ways. You don't need "find -nouser" to be able to find files without a legitimate owner, but it's clearly a functional enhancement to the original "find" functionality. As for the "philosophy of Unix", don't you think it's a bit ironic that the person posting it is mr. emacs? -tom \_ Either you're following the unix philosophy or you're trying to circumvent and short cut it and that way leads to madness and windows methodology and chaos. \_ well, clearly there is a "merit of having -S in ls" discussion going on, although the thread didn't start with that. But it's devolved into reiterating already-stated points. \_ So rather than being obtuse you're merely off- topic? \_ Obviously? So if I write a man page that says you don't understand the core concept of unix utilities then it becomes obvious? Sigh, I shall explain for the unwashed: the core concept you're missing is that unix is about having lots of little utilities that each do one thing really well. You create a stream of data from little util to the next via pipes and out pops the right thing at the other end. I know 'ls' and 'sort'. I know I can pipe from one to other. I know this works on every *nix system I might ever touch. This is called portability. Linux is the bastard child here, not the non-Linux real unixen you're deriding. Linux is following the Windows style of over loading programs with things that seem neat at the time but turn into bloated crap later. I like Unix. I accept Windows. I do not want my Unix bloated up into a half assed Windows a la Linux. Simplicity, son. KISS. \_ you dolt, yes I know about all that shit. "son". my point is simply about the usability issue. I don't care what other unices are doing, I'm saying that they should do this. Whoever wrote that man page obviously knew about the option and knew there were poeple wanting it. -S is not "bloated crap" any more than -t or -r. ls is probably the most common command users run. Listing files is what ls does, it should "do it well". I could write a man page that says vi is unnecessary because you have ED IS THE STANDARD! \_ Sorting on a date with sort is not the same as sorting on an integer such as size. Please explain in what way I am a dolt. Is it that I read your mind and understand what you don't understand to such a degree that you have nothing left to say but insult me? If that is the case, then yes, I am a dolt. \_ It sure is the same, son. Sorting on a date isn't algorithmically identical, so what, irrelevant. You're ignoring the big picture. I'm done arguing for today though. Btw ls could easily output the date in a sortable manner. Unix philosophy doesn't require factoring everything into as many programs as possible. \_ alias ls-S "ls -l | sort -n +4" now you can type "ls-S" in 5 keypresses! for common tasks, you can make the number of required keystrokes arbitrarily short or long. non-issue. \_ duh. of course you can make an alias. totally beside the point. of course you'd have to do more work to make it work just like a real "ls -S" would. \_ This is why after 10 more years, there will only be Linux and nothing else, because the other OS are simply too arrogant to do anything about it. Take for example the man pages on Solaris, I mean how much effort does it take to make it so that it will format according to your screen and does not produce the stupid 24 line page header every page? Everytime I look at the man page on Solaris I curse it. The linux one is so much better. One reason why SunOS is fading. \_ You know, I HATE working on Solaris. Nothing works the way that I'm used to without aliasing everything. However, when we were running our server on Solaris it never once crashed in the entire time I was in charge of it. I can't say the same for any of the Linux installs I've set up. \_ In 10 years, I think there still will be Windows and Mac OS. Your arguments for Linux and against other Unix OSs are the the same as the arguments for Windows/Mac OS and against Linux. Every time I read a man page I curse it. Hyperlinked help files are so much better. \_ personally, I find the statement "after 10 more years, there will only be xxxxx and nothing else... " to be pretty absurd in the context of any technological question. \- the amount of wrongheadedness in this thread is amazing. but rather than agrue, the youth ought to read ... --psb http://www.faqs.org/docs/artu/ch01s06.html \_ excellent. --scotsman \_ Yes! Finally! This should be mandatory reading before geting into core CS classes or getting a Soda account. \_ In 10 more years Linux will 'rewl' because the man pages format better than on Solaris? If that's the best you can come up with then just stick with Windows and reboot a lot. |

5/7 How do I make ls sort files by size like -t for time? thx \_ From man ls: The following is how to do an ls listing sorted by size (and shows why ls does not need a separate option for this): ls -l | sort -n +4 \_ use Linux, it's -S \_ I want to do this on soda! \_ download gnu fileutils, compile, presto. \- ls -ls | sort -n[r] --psb \_ ls -ls | sort -n[r] sort: No match. \- dont actually type the [], you doofus --psb \_ ls -l | sort +4 is more general. \- it's more fragile. ls -s always makes the sort field first. otherwise the field can depend on whether the group owner is listed etc ... varies by ls flavor, ls aliases etc --psb \_ well, I meant since it depends on block size it would fail by default for tiny files. \- fair enough, but really arnet you just looking for the biggest file 95% of the time. --psb \_ Add a -n for good measure. Not all platforms will detect an all numeric column, so "sort -n +4" \_ ok, but he said "want to do this on soda!" :) frankly though I think the man page is stupid and it should be an ls option for convenience. they have the other sorting functionality. \_ They have sorting for time becuase sorting human readable dates is difficult with other default command line tools. Sorting file size is easy. This is the UNIX way. many modular pieces you can piece together to do what you want. Linux makes you weak. --scotsman \_ it's a bunch of extra characters to type for a basic, common desire that could very easily just be in ls where normal people expect. (hey, why should sort have a field option anyway? you can just manipulate lines using 'cut' etc. It's the way real men do it.) \_ don't be a doofus--it's not like FreeBSD "ls" is "pure" (color "ls" doesn't make you weak, but sorting on size does?) -tom \_ I wasn't talking about purity. And I guess it wasn't clear that I was being facetious. But the point stands that to pull sort into ls with yet another command line option makes ls more tedious to remember how to use and postpones the newer user's learning how to use sort. And who uses color ls? --scotsman \_ how is it more tedious? If you don't want to use -S, pipe it through sort instead. -tom \_ I guess I'm just sick of interviewing IT drones who can't write a decent command line.. --scotsman \- how about adding a du flag that just means du all the directories under here but not the files. how about another du flag that is directories only in size order. and another that sorts based on number of files rather than cumul size.. --psb \_ Ah yes, I forgot; the only "official" command-line options are the ones that FreeBSD has adopted. Therefore it's OK to use "find -delete", but not "ls -S" -tom \- pure is BSD 4.3 --psb \_ color ls is the best thing since linux! just like color monitor is the best thing since monochrome green terminals. \_ Once you begin to appreciate color ls, you will never go back, like a lot of things. \- dired >> ls --psb \_ using sort -n +5 gets rid of the color, oh fuck, fuck!! \_ If you are using a terminal with black background, try LSCOLORS=BxDxFxdxCxdxdxBxBxBxBx and do ls -G \_ Cool, ls -lG / looks nice! |

I should mention that it does not matter where I put the actual docs directory, the links works fine if I open a file directly in that directory but does not work if I open it through a symlink. I don't know why it would be sensitive to symlink but it is. \_ If Mozilla thinks it's opening file://home/foo/bar.html, a relative link will open file://home/foo/baz.html. This is true whether /home/foo is a directory or a symlink to another directory; the URL is the issue, not the filesystem location. -tom \_ Well, no shit sherlock, of course it would be sensitive if the links are relative. Hover over the link and see what the browser is pointing to (look at bottom of browser window in Mozz).

Asshole. -tom \_ i'll just note that bad behavior on one part does not justify or excuse bad behavior on another, just as rudeness on one does not justify or excuse rudeness on another. \_ Yes. Unless it's tom. Speaking of resource abuse, whatever happened to the alumni donation thing? I'd like to donate maybe 50 bucks but I still don't see a PayPal link and what not. Maybe I should just donate to the Stanford computing facility. -guy doing CSMS@Stanford \_ there is a difference between what is expected and what is justified. \_ Being rude to tom is always justified. \_ since I ever met tom in 1992 he's been rude and inconsiderate. he has contributed very little except hostile, condescending remarks, and now this. It's not the first time, and it will not be the last. It has been 12 years since I've known him and very little has changed. I really think we should squish him. \_ "now this"? I put a file requested by another CSUA member into a directory intended to allow CSUA members to share files. How horrific! As for my contributions, I was CSUA VP for two semesters--what have *you* done? And there are files > 100MB which have been there for over 2 years; why do you care about mine? Oh, right, because you're an anonymous coward. Shit, I've been trolled. -tom \_ I don't see what anonymity has to do with the size of the file. And I certainly don't buy into anonymity as a justification for pointless ad hominem. Chill, dude. -mice \_ Why are you talking about the file? The post tom responded to is just an anonymous smear and request to "squish him". You're fucking insane if you think his response was somehow out of line. What ad hominem? Wtf is wrong with u people. \_ Uhm, did you even read the post the guy is replying to? Train harder, grasshopper. \- because not removing the file is "out of line" with arguing with the fellow in the motd. nobody is saying tom should be squished or shouldnt argue with this fellow. but he should have done something with the file. his stubbornness over this makes him either stupid or an asshole ... or possibly somehow psycho- logically disturbed. --psb \_ Because yours was the largest file. That was hard. Try engaging your brain occasionally. \_ Irrelevant. It's still a relatively small usage of the filesystem. \_ FYI, signing as "guy doing CSMS@Stanford" does not count as de-anonymizing yourself. You might as well not sign at all if you're not going to give your username. \_ I think that was about the donation part, not the tom part. \_ Speaking of resource abuse, whatever happened to the alumni donation thing? I'd like to donate maybe 50 bucks but I still don't see a PayPal link and what not. Maybe I should just donate to the Stanford computing facility. -guy doing CSMS@Stanford \_ Why do you guys always pick on tom? Just because he's a bit rude, hostile, and censors the motd like some nanny is no reason to abuse him all the time. Seriously, I feel badly for him. He's working as some IT peon at one of the greatest universities on the face of the planet and literally surrounded by people smarter and better educated than himself since he never graduated. Of course he's bitter and hostile. Why don't you guys just accept him as he is and let him feel important once in a while? He'll mellow once you accept him as one of us. \_ hahahahhaaha this has got to be one of the best responses I've ever read. It deserves the best motd post of the week. \_ you hypocrites sound like pathetic high schoolers \_ well apaprently there is space on /csua/tmp now, and moab*.avi is still there, so whatever. \_ So the moral of the story is: Most CSUAers are helpful and cooperative, but tom is a jerk. \_ Here is what is going on: Tom is proud of whatever is in that file [thus the helpful suggestion "why don't you dl it and see"] and he wants to keep it there to point to or for people to stumble on. If he were to delete it, putting it back without "someone asked me to put it there" would just look pathetic. No, I don't know why he doesn't just put it on a web page. \_ It's really simple. I'm not going to respond to some anonymous coward's attempt to disparage me on the MOTD. If someone wants to make it a personal request, I'll consider it. The file is a video made at the 2003 Moab MUniFest, and I think it could be of interest to people, but the original purpose of putting it in /csua/tmp was that randal wanted to see it, and I don't have personal web space where I can stick 300MB. -tom \_ You guys are bad.

I'm not saying your answer was not a possible right answer, but it's also possible there is some reason that's not feasible. Unlikely, but not impossible. Also, there's no reason to be a jerk. You could politely suggest your alternitive. I suppose this anwers my question as to why everyone wants to sorry your account. -jrleek \_ The person has a soda account, so of course it's feasible. You might say there's no reason to be a jerk--I say there's no reason to ask stupid questions. -tom \_ And so he posts after the op already posted why he didn't want it on a webpage. \_ The op is still a doofus. \_ The op's reasoning is flawed. This whole thread is stupid enough that by MOTD charter section 7 subparagraph B the op shall be subject to insults until such time as the thread is gone. The fact that it's also about Hotmail is just insult to injury. \_ Hey, can I help it if people I associate with make the mistake of using hotmail for email? In the future, the first question I ask when I meet someone will be if they use hotmail for their email. If so, I just won't associate with them. -op \_ You mean injury to insult? \_ No, he probably doesn't. \_ I'm surprised anyone would even mentioning sorry in in this context! I agree with Tom - given the OP's posting, "why not send links" seems a very reasonable question... \_ That's what I'm saying, it IS reasonable, but you don't have to be a jerk about it. As for the sorry mention, that's referencing yesterday's discussion. -jrleek \_ so if you dont have a hammer available, you'd rather insist on using the screwrdiver, instead of getting one? \_ I appreciate the suggestion to put the pics on a web page. There are 2 reasons why I don't prefer to do this. I don't want the pics publicly available. And I don't want them on my web site indefinately. If I send a link, the receiver might assume they will always be there. But I will eventually take them off the web. So, good suggestion, but I still prefer to email them. So, is there anyone out there with a hotmail acct that can answer my original question? -op \_ There's another reason people might choose to hurl insults at you at this point. It literally took me less than 100 seconds to go to http://hotmail.com, look at the FAQ, and see that any email under 1 MByte total is fine, as long as it doesn't put the user over their total quota. So you're ok if the user is not close to having a full mailbox, since you want to send less than .5 Meg. \_ The FAQ I found on http://hotmail.com says there is a limit of 1 Meg for outgoing messages. I doesn't say anything about incoming messages (that I saw), but I vaguely recall that there is some limit to the number of attachments an incoming message can have. \_ All this discussion, but no answer to the actual question. I guess hotmail users don't post to the motd. \_ you could have frigging mailed the stuff already and not wasted so much time. Just email once or 10 times in smaller amounts. what the fudge is it? It is only 200k total. Send it in one email doofus. \_ send yourself 20 small jpg files and see what happens. there must be some reason you're asking this if you don't think this will work. \_ I don't have a hotmail account. It's easier to ask on the motd than to get a hotmail acct just for this purpose. -op \_ Better yet: open a Yahoo Mail account. Send the pix one at a time to that account. When all of the pix have been received by the account, send the username and password to your intended target. Yahoo gives more storage than Hotmail anyway. |

3/18 Dear Dedicated Grandma of 5-Year-Old Boy: I saw what you did. And I applaud your determination to teach your grandson right, I really do. Its so refreshing these days, in a country where most parents work and leave their children to the care of strangers, that in some families a grandparent steps in to pass on their values. You are such a hero, Grandma. And Grandson will be all the better for it. You: elderly female, riding the L Taraval with your five-year-old grandson, sitting up front in those seats that face inward. Me: male in my late twenties, from a farm town in Southern California, unaccustomed to the ways of "the big city," sitting in the middle section of the train, in a seat that offered an open view of yours. There was a woman next to me. The train was moving, the scenery was dull. I looked over at your seats. And just in time. Your grandson reached deep inside his nose with his index finger and pulled out a huge, juicy nose fruit. He then began to contemplate eating it. This intention we could all see in his eyes, and it was confirmed as he slowly drew his adorned finger to his mouth. You, grandma of the quick reflexes, SuperGrandma I'll call you, you stopped him just in time! You grabbed his finger, removed the nose goblin, and. . . . ate it yourself. A nose nugget is a difficult thing to dispose of, to be sure -- especially a nugget of this size and obvious quality. So YOU ATE IT YOURSELF. Priceless. What was that boy thinking, not offering it to you first? Congratulations, Grandma. Lesson taught! Never mind that the woman on my right turned to me and said, Did you SEE that? Never mind that she then moaned, Im going to vomit. Never mind that I stopped riding the MUNI that very day, and decided to contribute to every kind of polution you can name by driving to work instead. What is important, Grandma, is that you taught that boy an important lesson in etiquette. N'est-ce pas? \_ Craig's list or your own experience? \_ This is fantastic. Thanks for making me laugh out loud. -John \_ you should consider a career in writing. this is good stuff. \_ I'm glad someone is teaching the next generation a lesson in sharing. That was heart warming. Thank *you* for sharing, too! \_ I prefer the one with Grandma getting her canary off in Savage Love. |

When I do the same thing in BASH, it prints a ":". How do I get the history-search-backwards/forward in BASH? THANKS! \_ man bash; Look for the section on Searching. \_ in bash and zsh, use C-r/C-s for emacs-style reverse/forward incremental search. \_ zsh also supports tcsh-style history-search-backward, if you want that. \_ Don't listen to these heathen. tcsh is the One True Shell! Bash is what linux weenies use because, well, uhm, Linus uses it so it must be the best! \_ Ranting aside, bash really is quite shitty. There's no real reason to be running it with all the other options out there. It tries to be everything to everyone, and ends up being internally inconsistent. \_ Bash is the only shell that is useable for interactive sessions, features a bourne-compatible syntax and ships by default on Solaris, most Linux distros and MacOS X. The only other option for interactive sessions is ksh, which isn't available by default on most Linux distros and MacOS X. (Before you say just d/l ksh or whatever other shell, try to keep in mind that some of us have to use systems where we cannot install/execute software that isn't approved or isn't part of the default install, so we have to be familiar with the tools that are almost always present). \_ Based on the descriptions online, I'm having trouble seeing what makes bash interactive and tcsh not and, FTM, what's the big deal about being interactive. Apologies for lack of clue. \_ Could somebody do me a favor and tell me what the word "interactive" means in this context. Apologies for my lack of clue but it's not like the thing can talk to you. \_ Why is it the only one usable? \_ It doesn't have a builtin spell checker, we know that from his post, heh. \_ bourne syntax is better for programming, not for interactive use. \_ kinda cool how the pro-bash clone eliminated dozens of other options as if his opinion was fact. i like him. he'll do well on the motd. \_ tcsh has no advantages over bash (save a memory footprint of ~ 200kB, which is meaningless these days). The fact that it uses c-shell syntax is a huge drawback. Some of us do use if, for, while on the command line. \_ tcsh has plenty of advantages over bash; better interactive syntax, for one. \_ name some other options that are available by default on most systems. \_ tcsh \_ what part of "cannot install/execute software that isn't approved or isn't part of the default install" didn't you understand? \_ it's not really hard to install your own shell locally and run it from whatever PoS login shell you're given (example: bash). \_ Since Panther, I've been using bash and I don't esp. like it, but i can't figure out if I don't like it out of lazyness/acustomedness to tcsh or some other reason.

1/26 I just transfered several thousand files from a Mac to a PC. Macs don't have file extensions so is there any UNIX utility (or PC utility) that will differentiate between word and excel files so that I can programmatically add the .xls and .doc extensions? "file" simply says "Microsoft Word" document. \_ write an applescript. Unfortunately, I don't know the syntax for grabbing creator codes from the finder. Maybe someone else on here does. Applescript documentation is horrible. \_ What I ended up doing was using perl to traverse the directory hierarchy. I changed all :'s to -'s (PCs don't like :'s) and add .xls extensions to each file. This is somewhat lame, but 95% of the files are excel files and I was able to do this in less than 10 minutes (I already had the perl readdir traversal code handy, I just had to find it)... of course, I did all this before asking on the motd bc i didn't think i'd find any useful information here. I'd still be interested in a nice solution (ideally, someone would tell me that I just need to upgrade my version of file) \_ you should rename the files while they are on the Mac. http://www.versiontracker.com/dyn/moreinfo/macosx/14404 \_ link not found and this is System 7 we're talking about. \_ DEAR GOD WHY??? Uh. can you transfer them to a more modern mac first? \_ It only took him 10 minutes this way. \_ 'file' depends on the 'magic number' which is stored in a file. you only really needed an updated magic file. \_ This came up on google under "automatically macintosh file extensions". I bet you can find more: http://peccatte.karefil.com/software/MacNames/MacNamesEN.htm \_ using perl, you can issue the file command recursively through your dirtree and dump the results into a text file. You can then open up the text file and issue a rename accordingly to each of the files it finds. Should take about an hour to write up in perl. -williamc \_ An hour? It should take about 5 minutes in any shell. On a bad day. Between commercials and surfing. This is a good time for sed/awk for those too lazy to use the search/replace function on their text editor. \_ Hmmm, apparently you don't do any "shell scripting" on a PC in Windows/DOS. This can be done in five minutes on a UNIX machine, but with Windows through a DOS VM box (assuming you're not using cygwin) I'd have to spend some time testing it to make sure it was functioning correctly. If using the find command you'd have to figure out how to dump the information into an intermediate text file and parse the contents. Regardless, I'd like to see your five minuts solution posted on the motd, it will be informative. Also, wtf does does your text editor have to do with identifying binary files??? Reading comments like these makes you think that the poster didn't understand the problem domain. -williamc \_ i'm not the guy above, but you might want to consider posting anonymously, lest people associate "williamc" with "talking out of his ass". cygwin often works *just fine*, and i don't see any reason to believe it wouldn't in this case. as the OP has already mentioned though, 'file' doesn't give enough information to distinguish between word and excel files. but even supposing it did, you would either want to use sed/awk to massage the output into an easier to parse format, or use a text editor to do it if you don't know how to use sed/awk. perhaps you should keep quiet instead of making an ass of yourself next time. \- ObEmacsDiredMode --psb \_ What I ended up doing was using perl to traverse the directory hierarchy.

I'd like to ask some questions about how it is working there. thanks. \_ last | grep "216.239" \_ why don't you post your login so they can email you?!? why should you get to be anonymous instead of them? after all, you are the one with the questions. \_ it's a cult. they wanted me to sell my house and move to mountain view to take a job there and were confused and insulted when i said i wouldn't do that. \_ I think living where you work is great...as long as you don't have to live *or* work in silicon fucking valley. -happily walking to work 3000 miles from SV \_ What silicon fucking valley? I never get enough fucking in silicon valley. \_ where do you work out of curiosity? \_ Yes I'm sure it is but to tell me I'm not getting an offer because I won't *SELL MY HOUSE* and move to mountain view is fucking ridiculous. To work at a dotcom. Sheesh. It's a cult, plain and simple. \_ What rationale did they offer for this? Would the commute have impacted your work that much? \_ Something like, "We like it when everyone lives close" which was not helpful. The guy who did my tech phone screen was some kid who had never worked anywhere but there and only knew "The One True Google Way" of doing everything. It was a miracle I was able to guess enough right answers and read his mind enough over the phone to not get dropped right there. So HR dropped me for not being willing to sell my house and move to mountain view because they're going to be the next netsca-- nevermind. It was stupid. They're a cult. I'm *very* happy I got a much higher paying job with fewer stupid people around. I wasn't looking forward to being some kid's dumping ground for projects he found boring. \_ how far did you get in the interview process? \_ too far. what a waste of time. if you need a job and they make an offer, take it. don't sell your home to join a cult. BTW, I believe today is the 25th anniversary of the Jones' Town massacre, speaking of selling your home to join a cult. \_ Anyone remember "Murder Can Be Fun"? - danh \_http://www.weeklyuniverse.com/2002/tempslave.htm |

11/11 ls -lt lists all files in a directory in chronological order. For files nearly a year old, it only lists the date, but not the time, of last modification. But it lists them in non-alphabetical order. Thus, I suspect it is indeed listing them in order of most recently modified. So, then, it presumably knows the modification time. How can I get it to list the modification time, rather than the year, for older files? \_ get the ls that comes with GNU coreutils. it shows both date and time, but only up to hour and minute. \_ Try -T, works on FreeBSD \_ Whoa, that's really useful, never knew about that; thanks! Too bad it's not standard. -!op \_ works here, but not on my machine at work. \_ which runs....? \_ Solaris \_ Solaris follows the POSIX standard \_ Maybe try /usr/xpg/bin/ls ? \_ Try tarring up the file and scping it to soda \_ As with all problems, this can be solved with perl: alias ls-lt to: perl -e 'chdir$ARGV[0]if@ARGV;opendir D,".";print scalar localtime $_\ ->[0]," $_->[1]\n"for sort{$a->[0]<=>$b->[0]}map{[(stat)[9],$_]}grep\!/^\../,readdir D' (note the \'ed ! to make your shell happy). Then you can just say % ls-lt /tmp % ls-lt etc. and get the full dates. --dbushong \_ or you might even be able to do tar tf on the tarfile |

11/8 UNIX question: Is there any elegant way to do something like command < foo.bar > foo.bar where command is something that modifies foo.bar ? \_ perl -p -i.bak -e 's/OLD/NEW/g' ? \_ not quite. but it's not very hard to write a little wrapper program that first renames the file to something else, then runs command on it, or something like that. \_ in csh: command < foo.bar > out ; mv out foo.bar. this is hardly rocket science. what sort of elegant were you looking for? \_ dd ibs=`ls -l foo.bar | awk '{print $5}'` if=foo.bar \ | command > foo.bar Oh, elegant? No. Do the tmp file thing. --dbushong |

11/2 Stupid question--nfs mount as root, between 2 FreeBSD boxes. How do I allow root on the client to chown files in the mounted directory? -John \_ nfs mount option...there is some default option that maps root. disable it. --aaron \_ actually its a NFS export option from the NFS server.

Thanks! \_ man spam \_ can I install spamassassin as non-root on a machine that I don't have root on, like... company machine, school, etc? \_ yes but it's easier with root. with some tiny clue you can do it as non-root. you're mostly changing paths around. \_ ok I just installed it with non-root. However it only filters 50% of the rules. Should I make it learn it on a frequent basis (e.g. sa-learn --spam mail/spam) or is there a better way? Also is razor a good thing to have? |

10/24 How do you guys deal with different backspace characters in different terminal programs? I have a screen where the terminal is set to erase = ^h, but then sometimes I use a terminal (on some other machine, say) where backspace sends ^?. Are there really any ways of dealing with this besides making sure every terminal I happen to use is configured to use the erase character I use in my screen? \_ Use bash. It's not 100% effective though, but modern versions of bash just accept both as backspace. |

10/21 Hi is there a small utility on unix that can replace a word in a file? \_ perl -p -i .bak -e 's/oldWord/newWord/' file. If you want to replace all instances of oldWord with newWord, use 's/oldWord/newWord/g' \_ Actually, without the g it will replace the first instance of oldWord in each line. The g makes it replace every instance of oldWord per line. -geordan \_ Lots. Try sed. \_ the oneline perl script works great with one file. Is there a way to have it process whole bunch files like *.*? \_ Um... perl -p -i .bak -e 's/oldWord/newWord/' * \_ uh no, got an "invalid argument" error \_ here's where you copy paste the exact command you used along with exact error you got, and we go from there. |

9/30 I'm not a very mathy person, but I've found myself in dire need of a good root-finding algorithm. I've currently got a piece of software that uses Mueller's Method -- but it sometimes generates whack results that crash a rather twitchy third party piece of software as it iterates. The curves I'm examining can be assumed to be monotonic. Can I do better than Mueller's, or am I SOL? TIA. -mice \_ Use Mathworld to look up 'root finding' and find the root finding method which will work best for the kind of function you have. Using mathworld for this sort of thing is a good meta-skill to learn. \_ you'd probably find a numerical analysis text more useful than mathworld. try checking one out at a college library if you can. there are not that many root-finding methods that are actually used much in real life. \_ One technique to explore-- see if you can parameterize your curve on some region of interest by a [0,1] lambda. I.e.. munge your algebra around until you can get a diff from root as a function of some linear parameter. If your curve is nice, consider golden section or binary search. Another thing to do is just chop up lambda into increments, evaluate diff, and pick the best guess at root (or refine search in a region of the best approx from a linear visit across lambda). Not the niftiest method in the universe, but it gets the job done. |

9/27 Say I want to kill processes older than x hours. If I make a list of PIDs, check the start time, and kill on that basis, there is a small possibility that that process will terminate after I've done the check but before I do the kill, and that another (possibly important) process will take on that PID, and I would thus end up killing this important process. Is there any way to avoid this race condition without going down to kernel level? Thanks. \- sure, lots of ways. check ppid, argv string, start time of process, etc. the rightway.easiest way probably depends on some details of how you are trying to do this but certainly you can with ps | awk/grep | (xargs|) kill. --psb \_ well, that mitigates it somewhat further, but does not remove the essential race condition. \- yes it does, if you do it correctly. or do you think something like PAWS isnt good enough either. --psb \_ no, it doesn't. it's still a race condition. pipes are not atomic. you should know better. there's still a slim chance that between the ps and the kill, the proc exits and another starts. -!op \_ If you check the start time like the first reply suggests, it should eliminate the problem. \_ yes, but what if time wraps around too? :9 \_ No, it's not atomic. Don't they teach Computer Science anymore? I haven't done real CS in years yet I still know a race condition when I see one. \_ There is a race condition, but it doesn't matter. Running kill on a nonexistant PID doesn't hurt anything, and if you've really got a system that can wrap around 100k PIDs in the time it takes to run your ps | ... | kill, you've got one whacked machine. |
