getopt/getopts and csh
Is there a way to get getopt/getopts to work in csh?
I know... csh is not a good shell. Nobody should be using it but I have to deal with old scripts already coded using this shell and therefore I have to do some maintenance to them...

Any ideas about how to get it to work? I did recode some sh scripts using getopts and didn't work for me :-(

maybe you should say WHAT doesn't work or post the code that doesn't work....

Well... It's not that simple to explain what's wrong but at least I can't get the outcome I'd expect with a very simple example. Here's the sample code that worked for me in sh shell:

Code:
#!/bin/sh

while getopts a:b:cde opt
do
        case "$opt" in
                a) echo "hello $OPTARG";;
                b) echo "hello $OPTARG";;
                c) echo "c flag";;
                d) echo "d flag";;
                e) echo "e flag";;
                \?) echo "Usage: $0 -c -d -e -a a -b b";;
        esac
done

And here's the same sample code translated to csh that didn't work:

Code:
#
!/bin/csh

while (`getopts a:b:cde opt`)
switch ($opt)
        case -a:
                echo "hello $OPTARG"
                breaksw
        case -b: 
                echo "hello $OPTARG"
                breaksw
        case -c: 
                echo "c flag"
                breaksw
        case -d 
                echo "d flag"
                breaksw
        case -e: 
                echo "e flag"
                breaksw
        default:
                echo "Usage: $0 -c -d -e -a a -b b"
                breaksw
endsw
end
