From man bash:
Quote:
getopts optstring name [args]
getopts is used by shell procedures to parse positional parameters. optstring contains the option characters to be recognized; if a
character is followed by a colon, the option is expected to have an argument, which should be separated from it by white space.
One character per option. If you need something different, you will have to parse the parameters in a different way. On the other hand, there are plenty of characters left in the alphabet, so why not just take
s?
