I'm sure this is something simple I am overlooking somehow. I'd like the ability to pass -options into my shell scripts. For example my file called "input.sh" I can do the following:
root# ./input.sh 1

and it will result:
root#./input.sh 1
You passed me a 1

Just like an init script, etc.

I would like to be able to do:
root# ./input -m 1

and have the -m specify a different result in the case statement. Like:

root# ./input.sh -m 1
You passed me a -m 1

#! /bin/bash
case "$1" in
1)
echo "You passed me a 1"
;;
2)
echo "You passed me a 2"
;;
*)
commands;
;;
esac

Thanks for any suggestions as always guys.

look into 'man getopt'

Thank vgersh. This looks pretty gnarly. I will have to poke at it with a stick a bit and see if it moves.

Actually its not that bad. On newer systems, try using getopts. Here is a link that provides an overview and examples for parsing options with case, getopt, and getopts

Excellent addition google, thank you.

It does indeed seem much more complicated than it really is.
