                     that it was pretty lame.

                     it was Tony Li's car.
                     I think that a plate that
                     said RFC1149 would be really
                     cool, provided you contributed
                     to it.

           a man page, then maybe you weren't getting any real use out of tcsh

3/5     According to the solaris sysadmin guide I need to be in single user
        mode to do a dump/restore.  I've tried dumping when I'm not in single
        user mode and it works fine.  Should I be afraid that anything bad
        might happen?  Anybody had any bad experiences with ufsdump in user
        mode?  Thanks.
        \_ It'll complain sometimes if a file changes while it's backing it
           up, but it basically works fine.  -tom
           \_ referential integrity cannot be assured if dump is performed
              in multiuser mode.
        \_ Do you care about data integrity? If you do, then you should be
           in single user mode, since you can better control the accesses
           to the filesystem.
           That said, if you are doing this at home on your personal box,
           with one user and maybe the web/ftp server running, its not a
           big deal.
        \_ just curious, can you force remount the filesystem into read-only
           mode, then dump it, then remount it rw?  Might solve the integrity
           issues, and only lose you last-access-time information.  -ERic

2/24    Is there a good reason why UNIX prohibits normal users from
troll   making NFS mounts?
troll   \_ Well, it's not as good as prohibiting ANYONE from making an
troll      NFS mount, but you have got to let SOMEONE do whatever they want on
troll      a system, NFS mounts, after all, aren't ALWAYS the wrong solution.
troll      (just usually).
troll   \_ Solaris automounter allows any user to mount a filesystem from
troll      remote host as long as it is exported to you. So there is a way
troll      to do this on unix.
troll         \_ automounter bad. very bad. evil. spawn of the devil.
troll            only bill's network neighborhood is worse.
troll            if you need automounter functionality use AFS (its free
troll            now). AFS good.
troll      \_ you don't do it, the autofs system does it for you.  you
troll         as a normal user just make requests to autofs.  you can not,
troll         as a normal user with normal user permissions, ask autofs
troll         to mount a NFS export on any arbitrary mount point, only
troll         on those mount points that autofs is configured to manage --
troll         say /net, /home, /project, and you can not tell autofs, as
troll         a normal user, what mount options to use --jon
troll         \_ That's what I mean jon. Being able to mount things under
troll            /net is still much better than not being able to mount
troll            anything at all.
troll   \_ If you could mount any filesystem you want, anywhere you want,
troll      then you could do something like mount your own filesystem on
troll      /etc containing a passwd file in which you know the root passwd
troll      and give yourself root.  (This is just one of many possibilities.)
troll      \_ First of all, both /etc and /etc/passwd already exist and
troll         they're both owned by root on that machine. You can't
troll         overwrite them. Second of all, if there were to be such
troll         thing as user-controlled NFS you shouldn't have any more
troll         permissions than you normally would. In other words, if I
troll         don't have permission to create a new file or directory in
troll         / I shouldn't have the permission to mount a drive at that
troll         location.
troll           \_ But I could remotely mount your home directory on my
troll              machine where I have root and su to the same uid/gid you
troll              have on the remote host and then fuck with your files
troll              over nfs as "you".  Depending on how the mount points
troll              are exported, I could do the same to root owned files
troll              as well, such as /usr, /var, and others.  Got the picture?
troll              \_ We're talking about user controlled NFS clients, not
troll                 servers. As an NFS server, I, as root, would never
troll                 let you mount my disk so that you can fuck around
troll                 with it unless you had a legit reason in which case
troll                 I would have created a little restricted sandbox
troll                 directory for you to muck around with. But I think
troll                 it would be a useful idea (and relatively safe) to
troll                 have a SMB-like user-controlled mounting of remote
troll                 filesystems. I have yet to see why this is unsafe.
troll                 I have an account on CSUA called jondoe. On my
troll                 Unix box at home I want to mount everything in
troll                 ~jondoe at CSUA by supplying my jondoe username/
troll                 password pair and everything in ~jondoe is mounted
troll                 on my home computer. CSUA will only let me access
troll                 files in ~jondoe with the same permissions that
troll                 jondoe himself would normally be able to access.
troll                 \_ Yes.  That's all well and good.  Now explain what
troll                    prevents me from setting up a jondoe account on _my_
troll                    home machine with _your_ uid/gui and mounting _your_
troll                    jondoe account.  NFS has what sort of security to
troll                    prevent this?  None.  Please explain why I couldn't
troll                    do this.
troll                    \_ First of all, even stock NFS controls what
troll                       machines you export to.  Obviously it would be
troll                       silly to export csua home directories to the
troll                       world with no restrictions, but if you trust
troll                       a particular machine, this isn't a problem.
troll                       And second, NFS does have the facility to
troll                       use public-key authentication, though it's not
troll                       often used around here.  -tom
troll                    \_ Because you have to have jondoe's password to do
troll                       this.  Think of it this way.  jondoe logs into
troll                       csua, and types some magical command called
troll                       "nfsexport home-machine-ip" which exports HIS
troll                       home directory to that IP.  Or, he can run
troll                       "nfsexport jondoe@csua", type in his CSUA
troll                       password, and get access to his files.  Yes,
troll                       NFS has minimalistic security, but it doesn't
troll                       have to be NFS, maybe another similar system.
troll                       Now explain to me why this won't work, and why
troll                       this system, which would seem very useful,
troll                       isn't in place.
troll                 \_ Yes!  This is exactly what I mean.  Why isn't this
troll                    done?                -original poster
troll                    \_ Can you think about the potential problems?
troll                    \_ jondoe is exporting. Different from mounting.
troll                       What was your question again?

                      have a SMB-like user-conhamstered mounting of remote
                      it would be a useful idea (and relatively safe) to
                      have a SMB-like user-controlled mounting of remote
                      filesystems. I have yet to see why this is unsafe.
                      I have an account on CSUA called jondoe. On my
                      Unix box at home I want to mount everything in
                      ~jondoe at CSUA by supplying my jondoe username/
                      password pair and everything in ~jondoe is mounted
                      on my home computer. CSUA will only let me access
                      files in ~jondoe with the same permissions that
                      jondoe himself would normally be able to access.
                      \_ Yes.  That's all well and good.  Now explain what
                         prevents me from setting up a jondoe account on _my_
                         home machine with _your_ uid/gui and mounting _your_
                         jondoe account.  NFS has what sort of security to
                         prevent this?  None.  Please explain why I couldn't
                         do this.
                         \_ First of all, even stock NFS controls what
                            machines you export to.  Obviously it would be
                            silly to export csua home directories to the
                            world with no restrictions, but if you trust
                            a particular machine, this isn't a problem.
                            And second, NFS does have the facility to
                            use public-key authentication, though it's not
                            often used around here.  -tom
                         \_ Because you have to have jondoe's password to do
                            this.  Think of it this way.  jondoe logs into
                            csua, and types some magical command called
                            "nfsexport home-machine-ip" which exports HIS
                            home directory to that IP.  Or, he can run
                            "nfsexport jondoe@csua", type in his CSUA
                            password, and get access to his files.  Yes,
                            NFS has minimalistic security, but it doesn't
                            have to be NFS, maybe another similar system.
                            Now explain to me why this won't work, and why
                            this system, which would seem very useful,
                            isn't in place.
                      \_ Yes!  This is exactly what I mean.  Why isn't this
                         done?                -original poster
                         \_ Can you think about the potential problems?
                         \_ jondoe is exporting. Different from mounting.

2/22    Is there any advantage of tcsh over bash? I've always used tcsh for
        my shell and sh for programming. I'm wondering if tcsh has anything
        (other than automatically setting $REMOTEHOST) that bash doesn't.
        \_ one thing I like about tcsh that bash doesn't have is you can hit
          ^D on an attempted file complete, and it will list possible
          completions.  Pretty useful if you dont remember the exact file name
          and dont want to have to abort and retype a commandline just to
          do a 'ls'. (well this isn't a default bash option, it may exist,
          I just find it easier to 'exec tcsh' than 'man bash') -ERic
          \_ in bash, you hit tab twice.  $ ls foo^I^I[expansion list returned]
             but you can get this particular interface in tcsh as well.  I
             imagine it's a holdover from csh filec. --jon
             \_ If you put "set show-all-if-ambiguous on" in .inputrc you will
                need to hit tab only once in most cases.
        \_ tcsh has a convenient %~ option for the prompt.  Does bash have
           a similarly simple counterpart?
           \_ what does the '%~' option do?
              \_ it prints your current working directory with respect to
                 your home directory (e.g.: ~user/somedir).  man tcsh
                 \_ Of course bash can do silly things like that. You can
                    put about anything in your prompt. man bash
                    \_ I did man bash and didn't see anything about this.  Is
                       there way to do it that is as simple as in tcsh?  And
                       as far as "silly things" goes, realistically, I think
                       that as far as important (ie, "non-silly") features go,
                       bash/tcsh/ksh are about the same, so it's the little
                       things that make the difference.

                          \_ this only works for directories off of your own
                             home dir, not off of other users'.
                 \_ okay. I use ksh, I'd use bourne shell if I could hack
                    in filec and arrow keys for history. This sort of
                    stuff is frivolous.
        \_ Use zsh.  The best of both worlds.  (In fact, all most all of both
           \_ /sbin/sh is the STANDARD shell! Real men know how to type and
              don't need fancy line editing. Use Bourne Shell as God and Steve
              Steve intended. Though Korn Shell is the spawn of the Devil and
              David Korn, its use can be tolerated on systems with clueless
              admins who think that /bin/csh (Bill must have been intoxicated

                  \_ those are why inetd is still running (which i assume you

                     Also, it allows for use of s/key, for when your dog eats

12/7    POSIX question.  Is it true that errno is only valid if a function
        fails?  E.g. I have something liek this:
           foo = strtoul(...);
           assert(errno == EOK);
        I'm getting an assertion failure even though everything is ok.
        Somebody told me that POSIX standard specifies that errno is only
        set if a failure occurred.  Is this true?
        \_ Errno is ass.  It is not thread safe.  Don't use it;
           if a function needs you to use it, don't use that function.
           \_ Errno is thread-safe in POSIX; the name "errno" gets #defined
              to a macro that returns the current thread's errno.  See errno(2)
              or /usr/include/sys/errno.h.
        \_ could be that somewhere in strtoul EINTR or EINVAL is being
           set. AFAIK, strtoul does not set errno. Rather it returns
           ULONG_MAX on failure. It can also return 0 and set endptr
           (2nd arg) to non-null on a failure (provided you use that
           feature). ----ranga
                   \_ whoa...
           \_ I'm asking about a more general question.  strtoul is just
              an example.  In general, is errno set to EOK if everything
              is ok?  Or is it's value undefined if there were no errors
              in the function.  Somebody is telling me that according to
              POSIX, errno is valid only if a function fails in some way.
              \_ errno is only set on an error. checking EOK is not a
                 valid method of know if a function returned successfully.
                 from the man page:
                 "Successful calls never set errno; once set, it
                  remains until another error occurs.  It should only
                  be examined after an error."

                       \_ no particular reason. I've always signed

              \_ If it's stalling in .cshrc, I think there is some option

                 the problem still exists. Since root has simpler dotfiles

                   \_ I was talking with a friend about this and the
                      opinion was that if we distribute the GPL'd .c file
                      with the intention that the user can link it in
                      with our source, then it becomes iffy enough
                      that someone can sue us if we don't GPL the
                      entire proprietary product.
              for free to anyone that asks, less medium copy costs.  I can
              still sell my proprietary product for however much I want,
              but I have to give it away free to anyone that asks.
                \_ No you don't - you have to include source or provide it
                   at a reasonable cost for media for anyone who has a
                   binary copy, but you don't have to give it away for free.
                   \_ "less medium copy costs"
        \_ Okay, so I've done some research on the GNU GPL, and the basic
           idea is that if you link GPL'd source with your product, then
           your product becomes GPL'd, and anyone can take your product's
           source and make an improved version of your product.  In other
           words the GNU GPL "encourages" free software, which leaves the main
           revenue stream for GPL'd software to grants and support contracts,
           and co.'s like Red Hat that would pay programmers to write GPL'd
           software.  Is that right?
           \_ there's also the GNU Library license.  take GNU libc.  one can
              link to it and still keep his or her code proprietary.  -dpetrou
           \_ Yes.  This is correct.  The GPL is an evil virus license.
              \_ Well, free software isn't a bad thing.  The GPL definition
                 and intent should just be more clear to the lay programmers.
                 \_ I'm not opposed to free.  I'm opposed to virus licenses.
                 \_ BSD is a free license. GPL (and variations) are not.
                 \_ This is what happens when you get a kook like RMS trying
                    to write a legal document to do something that's
                    questionably legal in the first place.

                          should be. The purpose of grep is global
                          regular expression print, it prints out
                          matching lines from a *FILE* or list of

                              of grep is to find something i'm looking for
                              but don't know where it is.  Sometimes that
                              means i don't know where in a file. sometimes
                              that means in a directory and sometimes that
                              means in a directory tree.  If i'm just
                              matching lines in the way you are thinking
                              i'm probably not using grep i'm usin PERL.

                                    purpose of grep is "global regular
                                    expression print", it is supposed

        how to config the other systems. Url or other pointers
        \_  I've set up IPv6, alternately IPSEC over IPv4,
           on FreeBSD with it.  Assuming they have raccoon (key mgt. daemon)
           finished by now, it works great.  Otherwise there are plenty of
           other IPSEC tools in the FreeBSD ports collection.  Kame is real
           good for tunneling v4 via v6, and ipf/ipnat work just fine with
           it.  -John
           \_ Thanks for the info. I got the freenet6 tunnel working from my
              nat box (OpenBSD) to the 6bone (at least ping6 seems to work),
              but now I want to setup my other machines with IPv6 addresses
              so that they can be on the 6bone as well. My reading of <DEAD><DEAD>
              pages is that I need to get a subnet rather than a tunnel. Is this
              true? Who should I talk to in order to get a subnet?
                \_ No, the subnet is behind either of your kame boxes.  The
                   idea was to let you have ipv6 internal routing, and have
                   a network-to-network tunnel/VPN as opposed to a host-host
                   or host-network tunnel or VPN.  The idea here is that the
                   machine (firewall, routing PC) running kame 's internal
                   interface is your default gateway--to access a machine
                   on the subnet on the other side of the tunnel will then
                   be transparent for you, since the kame tunnel takes care
                   of the ipv6 transport via ipsec ESP.  As I gather, kame
                   also lets you connect to the 6bone, which is a bunch of
                   people also tunneling ipv6 via v4 (sort of an ipv6
                   internet on top of the internet.)  Mail me for more info.

           \_ Thanks.
        \_ "Weird NFS problems" is not very descriptive. I have used
           linux as a nfs/samba server for a medium sized company
           of 200 people before and had no problems. -ausman
           \_ Okay, here is a list of my common problems:

              1. Under high CPU load 1-2 for 15+ min the NFS server
                 process stops answering. strace says that it is
                 hung on a lock or a read.
              2. Sometimes files become directories and visa versa.
                 When this happens, only a reboot of the client ws
                 solves the problem (can't unmount)
              3. When secure is specified, clients lose connectivity
                 to the server intermittently.
              4. On big directory copies ~ 1% .nfs* files created.

              I never had such problems when my NFS server was a
              Solaris machine. I could go back to that machine (SS10)
              but I can't afford to good sized disk for it.
              \_ Silly rabbit, solaris is for intel.
                 Can't you afford $70+shipping?
                 \_ I have Solaris 8 for x86, but I have been told
                    that PII 400 or greater for decent performance.
                    Also, Solaris for x86 is mostly geared towards
                    high-end SMP boxes.
                    \_ All bullshit. Never trust your source again.
                       If the CPU is good enough for free*nix, its good
                       enough for solaris, if you run the same stuff
                       on it. It's all about RAM. Solaris needs
                       16-32megs more RAM to be happy than your average
                       stripped-down linux install. If your box has
                       128 megs RAM, solaris x86 will perform very well
                       on it. Even 96megs, if you dont run emacs+netscape.
                       True, you 'll be most impressed if you have a
                       multi-cpubox. But otherwise, performance should be
                       remarkably similar.
                       \_ I've got a PII 350 and I'll be running it with
                          128 MB ram. It will be a server only. No X BS.
                          I like Solaris, but I'm a little concerned about
                          security. FreeBSD comes with tcp wrappers et al,
                          while securing a Solaris box is harder (isn't it?)
                          Anyone know of a good URL where I can get hardening
                          tips for Solaris (or FreeBSD)?
                          \_ So.. install tcp wrappers, why doncha?
                             Or download "sunscreen lite", suns free
                             actual FIREWALL PRODUCT.

                             about "hardening solaris", but it sucks.
                             The proceedure is identical to any other *NIX:
                             shut down services, remove setuid progs,
                             check perms on dirs, etc.

        the terminal gets all screwed up (underline/inverse don't stop where
        they should, etc); this doesn't recur when I do the same from
        solaris2.5.1->soda or from soda xterm to said linux box. Is there
        a way to fix this without root access? ('xterm' entries in the
        respective termcaps are the same, if that means anything
        \_ Are you sure you're using an xterm and not a dtterm?
           \_ Yes. Wouldn't touch dtterm if they paid me.
                \_ I think there was some weirdness with termcap in RedHat 6.0.
                   If that's what you're using, upgrade.  Make sure your
                   TERMCAP environment variable isn't set and that you have
                   "set term=xterm".  -tom
                   \_ This is RH6.2, I do NOT, once again, have root on
                      EITHER box, term=xterm, and TERMCAP is not defined. Any

                      EITHER box, term=xterm (as is TERM), and TERMCAP

                           by hand and do the stty yoursel,m too.
        \_ i have a similar problem between ANY non linux compiled xterm
           and linux. redhat needs to die. you can always setenv the TERMCAP

7/5     Is there a way to get a shell (tcsh if it matters) to "steal" a job
        from another shell? Ie: I start process X (in the background) from
        shell 1; then the connection through which shell 1 was opened dies,
        but the shell apparently never receives a HUP and continues running,
        with the process running as well; I then log in again and want to
        somehow get that process in the foreground of my new shell.
        \_ use screen
           \_ thanks, but anything that can work post-facto?
              \_ No.  This is known as process migration.  Some research
                 OSes (Amoeba, I believe, maybe Plan 9? (don't think so))
                 can do this, but not Vanilla Unix-Like-OS.
                 \_ what the fuck? this is NOT called process migration.
                    process migration is hard because it involves moving
                    process ACROSS MACHINES. he just wants to talk to the
                    pty the process was running on. this is an easy problem
                    and screen solves it. you have to be REALLY stupid to
                    come up with a reply like yours.
                    \_ So screen will talk to a process that's already been
                       left without a tty?  What's the screen command for
                       \_ No, it won't, but if you ran it in a screen window,
                          your terminal session could die and you could
                          reattach it later.  --dbushong
                \_ VMS (a non-research OS) did this 20 years ago.  It's no
                   big deal, just something Unix never picked up.
                   \_ i think it would be a pretty simple hack to linux to
                      do this. you need to reattach to the pty side of the
                      tty, and you need to change the pgroup of the process.
                      anything else involved? i'm guessing reattaching to
                      ptys needs a kernel hack. or maybe the mechanism is
                      already there. in either case, it's a simple hack.
                      someone should volunteer.
                        \_ That's the great thing about open source.  The
                           do-it-yourself nature.  Go do it.
                           \_ Yourself.

6/16    Solaris Question. Currently I have several diskless solaris
        boxes that mount thier root file system (/) from a rarp/bootp
        server. I have observered that if this server becomes
        unreachable, the diskless clients hang. In some cases the
        diskless clients won't come back even if the nfs server becomes
        reachable again. To solve this problem I wanted to have the
        diskless clients use a ram disk instead of nfs for their root
        file system, but documentation looks scarce. If anyone has
        done this before or knows a good URL, I would appreciate it.

4/26    I have one IP address on my DSL line.  I have three computers
        on my LAN.  I want to be able to telnet into any of these from
        an outside IP address.  How do I do this?  [Question re-phrased]
        [Does anyone know of a product that can route more than one domain
        on one ip?  I know this is possible with virtual hosting.  Im trying
        to set up three computers I can telnet to on my DSL line, which only
        comes with one static ip.]
        \_ This question makes no sense.  What you've seen is web virtual
           hosting but given that your DSL provider only provided you one
           IP address you cannot create 3 new IP addresses visible to the
           outside world.  The best you can do is create a subnet
           (192.168.*.*) and have a computer (Linux IPmasq, NAT, WinGate,
           whatever) perfrom some sort of network translation.  The reason
           why web server virtual hosting works is because it's really
           using the same IP address but the URL that the web browser sends
           to the server hints to which directory to look at.  For example,
                      suggest NAT software in which the telnet remaps are
           if I have a web page at I can request that
           dnai set up virtual hosting so that when a browser asks for
  it will actually return to the browser
  instead (although the person surfing the
           web can tell this).  How that's done is simply adding a DNS entry
           and reconfiguring the web serer.  But most services don't do
           that.  You cannot map a host name to an internal firewall's IP's
           port.  For example, you cannot create a DNS entry called
           <DEAD><DEAD> to map to <DEAD><DEAD>:22.
           If you want to be able to telnet to your three internal
           computers protected by the firewall, you can setup portforwarding
           which is supported by many OS's.  So you can have a port listenig
           on port 1234 of your firewall so that when you do a
           > telnet <DEAD><DEAD> 1234
           it will send all the packets to your internal computer.
        \_ I know Win2K server can do this, because I have it working now
           with your situation.  Incidentally, I asked the same question
           on the motd half a year ago and the responses I got were
           the equivalent of "huh, fux0r?" and "fux0r me".
                \_ Win2K isn't magic - any NAT software can do this, but
                   you'll have to map different ports to different hosts
                   (i.e. telnet NAT 23 goes to host a, telnet NAT 123 to
                    host b, telnet NAT 223 to host c)
                   \_ Yeah, but Win2K has it nicely dumbed down.  Please
                      suggest software in which the telnet remaps are
                      easy with the matching OS name.  Thanks! =)
           \_ uh, the "product" that can "route" more than one domain to
              one IP is called "DNS", and that doesn't stand for "Digital
              Nervous System" you stooge.  -tom
              \_ tom, as you've pointed out, the question has some problems.
                 Nevertheless, you can set up Win2K server to route
                 telnets to your single DSL IP to an IP in your internal LAN.
        \_ the question is stupid and will be deleted in about 20 minutes.
                \_ Don't be a doofus.  The guy just wants to know how to do
                   NAT.  Just because he doesn't know the exact right question
                   to ask doesn't make it a stupid question.  If he knew
                   what NAT was he probably wouldn't have had to ask how to
                   do it.
                   \_ No he doesn't you doofus. You cannot solve this with
                     NAT, because he stated he has ONE IP ADDRESS globally.
                     You need a reverse-proxy, or plug-gw, on a
                     real operating system.

              the ACLs apply to. It seems like I'm missing something obvious.
        \_It's my _guess_ that OpenLDAP doesn't have a cool like app or
          GUI to create users (unlike Netscape or other directory servers).
          But since LDAP users are just entries in the directory, the
          common way to do it is to use your favorite text editor to create
          a LDIF file and use some utility to read the LDIF and place the
          entries into the directory. (LDIF is also much better for adding a
          lot of entries (users), you'll be sick of the GUI really fast.)
          See for some more
          info. You may need to dig into the schema and the documentaton
          for the LDIF format (on web somewhere) if you want something

           'clustering software' that makes it so these machines are all

                 solution does not neccessarily do clustering.

        means that I should do something like the following:

        ifconfig eth0 -broadcast -multicast

        Another point was that RPC services should be disabled on
        border systems. My understanding was that a border system
        shouldn't server files via NFS, but mounting was okay. If I
        need to mount directories, should I be firewalling the RPC
        \_ -broadcast means something other than 'forwarding directed
           broadcasts'.  In fact if you actually turn that off you may
           break important broadcast based protocols like ARP. If you're
           on a linux box you really want to do something more like:
           echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
           \_ Thanks. Do you know if this works with 2.0 kernels or is
              it just 2.2 kernels? Also, I'm assuming that -multicast
              is okay.
              \_ Doesn't look like 2.0 kernels have the option.  I'm assuming
                 you dont need multicast for things like MBONE so yeah
                 just turn it off too. -ERic
                 \_ I'm not using MBONE at home. I only have 384/128 ADSL,
                    so its just not fast enough. I guess I will have to look
                    at the 2.0 kernel compile options to get something similar
                    to ignore broadcasts feature.
                    \_ you'd probably do a lot better to just set up a
                       lot of ipfw rules to block out any traffic you dont
                       really need. -ERic

        \_ Yet another Bash MS article, so what?
        \_ Everything in here is wrong except the bits about
           "what", "another", and "bash".
           \_ yeah tcsh is way better than bash.

2/23    What is a good power-user (as opposed to dummy) level unix book for
        someone whose skill is a bit rusty due to years of neglect but want
        to get back in shape just for getting work done efficiently?
