  • @saint1729 Sure, it works on any operating system (even on Windows) that you have with bash installed, you just need to execute it. Commented Mar 26, 2020 at 15:22

    Cool. It worked for me. But, the key needs to be only one character. I wasted almost an hour figuring this out. Commented Mar 26, 2020 at 15:40
  • Great example, wasn't clear to me what the single characters referred to at first. Another example for those stuck: while getopts "f:b:k:a:s:" opt do case "$opt" in f ) parameterFilepath="$OPTARG" ;; b ) parameterBucket="$OPTARG" ;; k ) parameterKey="$OPTARG" ;; a ) parameterAccessKey="$OPTARG" ;; s ) parameterSecretKey="$OPTARG" ;; ? ) helpFunction ;; # Print helpFunction in case parameter is non-existent esac done Commented Jun 10, 2021 at 10:00
