Unlike reported here, getopt does not die when it gets an unknown option but
continues parsing:
$ getopt -o abc -- -a -f -b -g -c
getopt: invalid option -- 'f'
getopt: invalid option -- 'g'
-a -b -c --
You can use the -q option to surpress the error messages.
That being said, you can use a '--' argument to separate options:
$ getopt -o abc -- -a -f -- -b -g -c
-a -- '-b' '-g' '-c'
Ie. everything after a '--' does not get parsed and could be sent to another
script.
An example of this:
# Invoke as wrapper [WRAPPEROPTION]... -- ORIGINALARGS...
# Wrapper options are here -a and -b, just to demonstrate
# Example: wrapper -a -- --orig option -here -a
# This calls: original_program --orig option -here -a
TEMP=`getopt -o ab -n 'wrapper' -- "$@"`
if [ $? != 0 ] ; then echo "Terminating..." >&2 ; exit 1 ; fi
eval set -- "$TEMP"
while true ; do
case "$1" in
-a) echo "Handling -a in the wrapper"; shift ;;
-b) echo "Handling -b in the wrapper"; shift ;;
--) shift; break;;
*) echo "Internal error!" ; exit 1 ;;
esac
done
original_program "$@"
