THanks for the reply......! but erm....
I literally just started shell scripting when I started this... so alot of what you posted is confusing me.... can you elaborate some? Im worried that since i used things like $1 and $2, its going to go haywire when its done w/ the multi utility. What if it needs to use $5 and $6 instead?....!
My C version was a while loop with an if/else chain inside it...I see thats whats happening here also
Let me pop on a unix server and check out the getopt manual... Im not at my linux computer right now...
thanks again !
EDIT:
hmm im sort of seeing how this works.. based off the manual, and google!
When I get back to my Linux machine later... ill give it a whirl... but will it be something like
while getopts r:f:c: o
do case "$o" in
r) right.s ;;
f) findtext.s;;
c) count.s;;
?) *help like message*
esac
done
??
Im not seeing how I will get proper arguments passed to the scripts this way though....

CHSH(1) User Commands CHSH(1) NAME
chsh - change your login shell SYNOPSIS
chsh [-s shell] [-l] [-u] [-v] [username] DESCRIPTION
chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one. chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries. OPTIONS
-s, --shell shell Specify your login shell. -l, --list-shells Print the list of shells listed in /etc/shells and exit. -u, --help Print a usage message and exit. -v, --version Print version information and exit. VALID SHELLS
chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you are root. EXIT STATUS
Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid. SEE ALSO
login(1), passwd(5), shells(5) AUTHOR
Salvatore Valente <svalente@mit.edu> AVAILABILITY
The chsh command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. util-linux July 2009 CHSH(1)
