if statement with or's in it.

Shell Programming and Scripting

I'm trying to run an if statement that takes multiple case's

if [ $# -eq 0 or "$1" = '--help' or "$1" = '-h'] ; then

Thats the current cost i'm using I've tried a few different versions but its throwing up errors...

Can if be used with multiple or or statements ?

Also is it possible to have multiple options to point to the same thing in a case statement ?

i.e. instead of --help) I could have -h or --help) something like that ?

Thanks.

well, the or option, at least in ksh, should be "-o" NOT "or"

if if [ $# -eq 0 -o "$1" == '--help' -o "$1" == '-h']
then
  ....
fi

case $1 in
  ''|'--help'|'-h') ...............
                      ;;
esac

However, "getopts" is meant to parse options

If ksh is being used, this will also work:

if [[ $# = 0 || $1 = ?(--help|-h) ]] ; then
