2/14    Is there something equivalent to "cp -i" for tar?  I just overwrote
        my project tar file, and I'd like a confirmation before it tries to
        write to an existing file.
        \_ How about untaring to a temporary directory and then cp -Ri the
           files to the intended destination?
           \_ That would be decent, but I was thinking it should have
              something more alias-able. I was actually trying to type
              "tar xf myproj.tar", but I typed "tar cf myproj.tar", which
              created an empty tar file.  Bloody stupid.
        \_ Set noclobber in your shell and get in the habit of doing
           tar cf - > file.tar
           \- you should be able to do something with tcsh's programmable
              completions. exactly what to do depends on what behaviour
              works for you. you could have it offer to complete with
              tar t and tar x but not tar c. i often do:
              lstar   tar -tvf !*
              mktar   tar -cvf !*
              tarcp   tar cf - !:1 | ( cd !:2 ; tar xfBp -)
              \_ That should be cd !:2 && tar xfBp -, or even easier (and though
                 you get large warnings in the manpage, I've never had this
                 fail on any tar or OS): tar -C !:2 -xfBP -     --dbushong
              untar   tar -xvf !*
              zlstar  gzcat !* | tar tf -
              zuntar  gzcat !* | tar xvf -
              ok tnx --psb

9/20    How do I change my shell? chsh says "Cannot change ID to root."
        \_ /usr/bin/chsh does not have the SUID permission set. Without
           being set, it does not successfully change a user's shell.
           Typical newbie sys admin (on soda)
           \_ Actually, it does: -rwsr-xr-x 1 root root 37552 Feb 15  2011 /usr/bin/chsh

9/24    How come changing my shell using ldapmodify (chsh doesn't work) doesn't
        work either? ldapsearch and getent show the new shell but I still get
        the old shell on login.
        \_ Scratch that, it magically took my new shell now. WTF?
           \_ probably nscd(8)

4/27    I wrote a little shell script to collect iostat data:
        #!/bin/bash
        DATE=`date +%m%d`
        DATADIR=/var/tmp/user
        OUTPUTFILE=$DATADIR/$DATE.out

10/24  What's an easy way to see if say column 3 of a file matches a list of
       expressions in a file? Basically I want to combine "grep -f <file>"
       to store the patterns and awk's $3 ~ /(AAA|BBB|CCC)/ ... I realize
       I can do this with "egrep -f " and use regexp instead of strings, but
       was wondering if there was some magic way to do this.
       \_ UNIX has no magic. Make a shell script to produce the ask or egrep

5/19    If script A runs, and calls script B ..... is it possible for me to exit\
        script A based on results of script B and not continue?
        \_ assume any shell
        \_ Yes.
           \_ without passing the result to some stupid temp file?
              \_ It sounds like you want "scriptb || exit", which will run

8/18    Hi again, new freebsd guy here again, in bash I was able to go
        LD_LIBRARY_PATH=/opt/foo/lib ./runmyapp
        I managed to do this in tcsh by using setenv in a shell script
        that setenv's the lib path and then executes $1, just wondering
        if there was a way to do it in 1 line from the cmd line as in bash?
        Thanks, btw %2c or %3c worked.  Freebsd, tcsh and vi forever!

7/22    Why does everyone's 'mail last read' date say Jul 19th? even for people
