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

       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.

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?

8/20    When I use rsync to backup, it's pretty cool except in cases where

        directories (by checking for children files), or at least
        move them to a dated directory?
