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.

10/24  What's an easy way to see if say column 3 of a file matches a list of

       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

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!

2/5     I like Adobe Flash. When written correctly, it scales along

        fan of CSS/HTML, which for the most part, look wildly different
        between browsers, and don't even work consistently or
        correctly at times. So why do so many people (like Steve Jobs)

11/29   I'm experimenting with virtualization, and as a poor college student
