5/8     Hello everyone!  This is Josh Hawn, CSUA Tech VP for Spring 2012.
        About 2 weeks ago, someone brought to my attention that our script
        to periodically merge /etc/motd.public into /etc/motd wasn't
        running.  When I looked into it, the cron daemon was running, but
        there hadn't been any root activity in the log since April 7th.  I
        looked into it for a while, but got lost in other things I was

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

7/29    Happy Sysadmin Day
        \_ our "sysadmin" today deleted /home. When we asked her why
           she said she didn't do it. When I checked the sudo logs,
           I found these two commands in order:

4/22    In Linux is there an easy way to rename the scripts in /etc/rc?.d ?
        For example I want to set all the /etc/rc?.d/S91apache to S100apache
        so that it'll run the ramdisk BEFORE going to apache.
        \_ Sure, just move them.
           \_ I mean is there a script that will rename all of them
              for me? Like: setrc apache2 0 0 1 1 1 1

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!

2/10    I have an sh file that does a mount.. the mount does an

        from xml) using shell script instead of python/perl?

        which i can easily extract key/value pair.  can i achieve similar

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
