How can I make bash deal with long param using “getopt” command in mac?

Question

I want to make my bash script deal with long parameters. I found getopt, but it isn\'t supported in OS X. Can anyone tell me why getopt was implemented

Answer 1

There is a brew bottle for getopt.

Just run brew install gnu-getopt.

You can either specify the path for it like /usr/local/Cellar/gnu-getopt/1.1.6/bin/getopt

Or use brew link --force gnu-getopt so it will be linked in /usr/local/bin/

Just be aware that forcing linking might be corrupting your system (as it replaces the system getopt by the gnu one).
