Using getopts in bash functions

Looking to use getopts to help parse the command line args of your bash function? You'll need to make sure to define OPTIND as a local variable or it will be affected by other scripts running in your terminal session.

function myfunc() {
 local OPTIND # Must be local
 while getopts ":ab" opt; do
 case $opt in
 a) echo "using option a";;
 b) echo "using option b";;
 esac
 done
}
