8/3     How are you folks with NetApps backing them up? Dump? NFS? NDMP?
        Which software? Legato, Veritas, something else? Would you buy the
        same software again? I use Legato and I'm less than thrilled.
        \_ NetBackup (which uses NDMP) works pretty well if you can dedicate
           a drive just to it. That is, if you have a library with 4 drives,
           1 drive must be dedicated to NDMP clients
        \_ Buy 2, mirror.  Put a third off site.  Mirror.

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.  See the section ARITHMETIC EXPANSION
              in the bash manpage.  --mconst
              \_ Thanks.  I would have used Perl if I had thought that
                 I would need math functions.
                 \_ It's never too late to do the right thing.  It'll only
                    be harder to convert later.
        \_ bc (use a here document), note you have to define your own
           abs function.

        I have some files described by *.out and I want a nice scripty way to
        trim the last line off of each of them.  What's a good way to do this?
        \_ sed. $d
           \_ It would seem I'd need a pattern defining the last line for that
              to be helpful.
              \_ Erm.  try it out.  "sed '$d' filename"
                 \_ Thanks.
        \_ foreach i ( `ls` )
                mv $i `echo $i | sed s:.out::g`
           Warning, this only works in csh.
           \_ in that case, just do foreach i (*.out).

7/28    bash v3.0 is out:
        \_ Ah, a new version of a crappy shell.  Thanks Linux!
           \_ It comes standard on most linux distros so it must be the best!
                \_ It has pretty colors!
           \_ While I agree that bash might be overkill scripting, some of
              its features do greatly enhance usability (unicode filename
              handling, auto completion of filenames w/ spaces, &c.) 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.  Anything more than a few
                       lines of tcsh belongs in perl or some other real
                       scripting langauge.  Bash should die.  It's a
                       bastardized POS.

7/26    is there a way to list the file in your user space that has the largest
        size?  (Thank you all for the help except that idiot posted the rm
        \_ rm -Rf ~/
           \_ does anyone ever use R instead of r?
        \_ ls | sort | head
        \_ ls -lR | sort +4rn     But this won't tell you which directory
                                  the files are in.
        \_ du -k $HOME | sort -nr -k1,1 | head
           This should give you the files sizes of the largest files and
           directories in your home directory. If you want just files:
           { find $HOME -depth -type f -print0 | \
             xargs -0 ls -l | sort -rn -k5,5 ; } 2> /dev/null | head
           BTW, -print0 and xargs -0 only work on *BSD, OS X and Linux.

           \_ 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

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.

                \_ 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.

                   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\

                \_ 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

                           regexp.  The entire line need not match regexp,
                           but only contain it.  But I want the entire
                           first line (that contains a match to regexp) to
                           be essentially overwritten by the next line that

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.:
               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

                    quota problems.
        It works just fine, but I found 1 occurance of the following in my
        log file:
          expr: No match.
        How can expr generate a "No match error"?  Presumably the quota
        command yielded something like a '?' where there should have
        been a number.  But how would that be?
        \- close, but wrong shell metachar. if you are above quota, awk
           will return #####* for the usage. i note also expr may choke
           on large numbers. you may also be able to use this:
                If quota exits with a non-zero status,
                one or more filesystems are over quota.
           if you dont care about the actual numbers, you can do something
           along the lines of:
           quota | grep `dirname $home` | fgrep \*  > /dev/null && \

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

5/18    Sick and tired of people writing over your file? Now motdedit2
        is available at ~kchang/bin/motdedit2. It does aggressive append
        merge where no lines are deleted. In addition, there is a flag to use
        to "restore&merge" your last change. For example, if someone nukes
        a portion of the motd after 30 min, you can still "restore&merge"
        your previous editted file and the current file by typing
        "~kchang/bin/motdedit2 -r".  Any bug report to me.

           to say is so much more important than the drivel of others that it
           is worth *replacing* one set of drivel with another set of drivel?
           The rest of us have managed for years without any motd destroying
           scripts at all.  Just kick tom off soda and the motd will survive
           brutal censorship much longer.  Of all the censors he's the only
           one I've seen who has the time and the anal retentive nature
           required to "win" at motd deletion who will keep checking every
           30 seconds and re-destroying the motd until everyone else gives up.

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

                 \_ 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

        \_ 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

                 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

           intrusive the anti-virus programs are.  That's what you're talking
           about but worse.

        the screen to scroll. It makes things easier to read. Anybody know
        of a program like this? Otherwise I'll write my own. Thanks.
        \_ tail -f | more.  And you're a dork.
           \_ That requires user interaction. not what I want.

           with its own results.
        \_ sounds like you want jump scrolling as a less option.  Rather than
           scroll the screen for each line, scroll by say half a screen width
           and then don't scroll again until bottom of screen is reached. I'm
           kind of surprised that isn't already in less (yes I did RTFM).
           \_ what are you talking about? less is a pager, it doesn't scroll

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

              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.

                       \_ 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

                             to the original "find" functionality.  As for
                             the "philosophy of Unix", don't you think it's

                                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-
                 \_ 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
                    \_ excellent.  --scotsman

                       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

                                   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?
                                   \_ how is it more tedious?  If you don't
                                      want to use -S, pipe it through sort

        top node are all referring to the directory for the sym link instead
        of that containing the docs.  This doesn't happen for other html files

                 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.

                    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

        admit it compresses a lot better than gzip, and while it's hecka

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?

        \_ This is fantastic.  Thanks for making me laugh out loud.  -John

3/8     solaris NFS question.  I have two servers A and B.  Both of them
        mount each other's disks.  I disabled nisplus and modified the
        vfstab.  It works fine.  But if the machines are rebooted, it'll hang
        waiting for each other to come up.  How do I configure NFS to time
        out and not keep retrying?  I can't even get a login screen if
        machine B is down when I reboot A.  Thanks.
        \_ Don't do this. Say no mount at boot for machine A. After you boot
           machine A boot machine B. Then manually mount on machine A. You can
           obviously write a init script and stick it with the appropriate
           runlevel that check for machine B before it mounts.
        \_ Soft mount, but this seems like a rather kooky setup.
        \_ I've had to do stupid shit like that.  What I did was write a
           startup script that only tried to mount if the remote machine was
           already proven up (pick your favorite network test).  If not then
           it waits 5 seconds and tries again.  Put this on both hosts.

        programmatically add the .xls and .doc extensions? "file" simply says

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.
