pattern matching in shell script 2

[fireant]

Hi,

is this the correct and most concise syntax to match an argument to just two items?

if [ "$1" == "-[dD]" ]; then

ACTION
fi

I want a more concise version to the one below that's why i'm asking.

if [ "$1" == "-d" -o "$1" == "-D" ]; then

ACTION
fi

TIA,

Louie C.

If you're not familiar with it, you may want to check out getopts...

man bash or ksh and then search for getopts

case is the facility you want, getopts, as previously
mentioned is the way to handle complex options given to
a script via args but generally getopts uses the case
construct for interpreting and command logic.

Thanks to both of you guys and sorry for the late reply.

I'm gonna look at this getopts builtin and let you know if I'm successful.

Thanks again for pointing me in the right direction! Louie C.
