10/14   how do i do this in bash: alias  cd='cd !*;ls'
        \_ cd() { builtin cd "$@" && ls ; }
        \_ are you insane?
        \_ why do you want to do that?
        \_ stop using bash
           \_ I'm a tcsh user, but have been looking at bash. That's one of
              the things that I still don't know how to do in bash.
                \_ Why would you possibly want to change from tcsh to bash?
                   If Linux didn't ship bash as the default no one would be
                   using it today.  You're not improving your life by going
                   from tcsh to bash.

4/27    I wrote a little shell script to collect iostat data:

        DATE=`date +%m%d`

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" ]

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!

1/20    I have a rather common shell-scripting problem, but I am not sure
        how to do it in csh/tcsh.  I want to check the ctime (last
        modified time) of a file.  If it is older than, let say, 1
        hours, do something, older than 3 hours, then do something +
        something else.  Any hints on how to do this?  do i need to
        convert it to epoch to perform such manipulation?  thanks

1/20    I've been using tcsh as shell program tool (i know, bad shell to
        do scripting).  One thing I've noticed when I extract xml file
        is that the variable type automatically change from
        integer/string to... almost an array-like data structure when
        the output of the xml key/value is more than one (it's more
        like a string separated by space, but I was very impressed as

1/13    I am writing a commandline parser for a class and I could use some
        tips for algorithms to use. (The project is over and done so I am
        not cheating, but I am dissatisfied with my end result.) I STFW and
        didn't come up with too much I liked. I read the source for some
        shells like tcsh and that is *WAY* too complicated and relies on
        a lot of other code. I know that browsers and other apps have
