Using getopts to process long and short command line options

Question

I wish to have long and short forms of command line options invoked using my shell script.

I know that getopts can be used, but like in Perl, I have not

Answer 1

The built-in getopts can't do this. There is an external getopt(1) program that can do this, but you only get it on Linux from the util-linux package. It comes with an example script getopt-parse.bash.

There is also a getopts_long written as a shell function.
