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
        while true

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

12/8    Is there a bash equivalent to tcsh's history-search-backward ?
        \_ There's something similar called... history-search-backward. It
           is a bit more limited, in that it only searches for strings and
           not glob patterns. You may find reverse-i-search to be useful also.

8/18    Is it possible to truncate your path name in your prompt in tcsh?
        Tsch veterans REPRESENT!  I know this is how to do it in bash:
        # truncate path: returns $1 truncated to $2 chars, prefixed with ...
        truncate_path () {
                if [ -z "$1" -o -z "$2" ]
                then
