getopts — Parse shell options from arguments. Note: This command does not support longform options and thus us

Check if an option is the first set option in the current context

getopts {{x}} {{opt}}; echo ${{opt}}

Check if an option is set in a string (specified option must be the first element of the string)

getopts {{x}} {{opt}} "{{string text}}"; echo ${{opt}}

Set an option to require an argument and print them

getopts {{x}}: {{opt}}; echo ${{opt}} $OPTARG

Check for multiple options

while getopts {{xyz}} {{opt}}; do case ${{opt}} in x) {{echo x is set}};; y) {{echo y is set}};; z) {{echo z is set}};; esac; done

Set `getopts` to silent mode and handle option errors

while getopts :{{x:}} {{opt}}; do case ${{opt}} in x) ;; :) {{echo "Argument required"}};; ?) {{echo "Invalid argument"}} esac;; done
