I didn't know that -- would work. The documentation didn't mention that.

The line "*) makepkg_args="$makepkg_args -$arg $OPTARG" ;;" is still wrong though as doing "--" will end getopt and then makepkg is called with $ {*:$OPTIND} meaning that the parameters aren't handled by the getopts loop. Instead, how about this patch? It fixes the usage and removes the broken line.

Sure, the code is clearly wrong here.

This might be confusing if you're not familiar with the syntax for the end of options marker. You might want to reword this to make it more clear what you're referring to. Perhaps something like: Arguments passed to this script after the end-of-options marker (--), will be passed to makepkg.

As far as I can tell it would have never worked this way because according to the specifications for getopts [1] if there is no ":" at the start of the argument list $OPTARG will not be set and $arg will be set to "?", but if there is a ":" $OPTARG will be set to the unknown argument. Unfortunately this means we can not easily get the argument to an unknown option.

This works just fine if you use the end-of-options delimiter to exit the getopts loop, e.g.:

makechrootpkg /path/to/chroot -- -R
