[ast-users] [ksh93] Is it safe to use getopts in both global scope and functions simultaneously?

[Clark J. Wang]

Is it safe to write scripts like following since OPTIND and OPTARG are
global(?) vars?

function func1
{
    while getopts "ab:" opt; do
        ...
    done
}

function func2
{
    while getopts "ab:" opt; do
        ...
    done
}

while getopts "ab:" opt; do
    case $opt in
        a)  func1 ... ;;
        b)  func2 ... ;;
    esac
done
