Script Input Flags

[Grizzly521]

Hi. Im wondering if there is a way to use flags when starting a script.
Something like this.

Script -a -b 10

Right now Ive got something like this.


while getopts ab AA
do case $AA in
a) var="value"
;;
esac
done


So with that code I can only use flags ( -a -b ). Can I do the -b 10 so it will store say varB=10?

See the man page for your shell for details (as getopts is usually a shell built-in), but briefly, if you follow an option with a colon in the getopts string, it will set $OPTARG to the value of the next parameter on the command-line.

while getopts a:b: AA
   do case $AA in
       a) var="$OPTARG"
       ;;
   esac
done
