    Default [OT] How do I execute script in different shell?

    Hi,

    Sorry to post an off topic question, but it's a quick one, hope you can
    help.

    Say I have a shell script shell.sh:

    $!/bin/sh
    echo $SHELL

    From a bash shell, how do I get

    bash to execute the script
    ksh to execute the script
    sh to execute the script

    Yes, if it's not obvious already, it's a question from Computer Science
    course. The answers weren't available, so I wasn't sure if I got it correct
    or not...

    Sorry for the bother, hope you can help

    Thanks

    Robo

    First replace the initial dollar sign by a hash ('#') then enter:

    for shell in bash ksh sh; do
    export SHELL="$shell to execute the script";
    shell.sh
    done

    Please don't blame it on me if that doesn't answer the question you
    intended to ask.
