Won't work. 'ls -o' is already a valid command, so 'ls -fo' is the same as 'ls -o -f' or 'ls -f -o'. You can't start a long-option name with a single dash; at least, not in coreutils which uses getopt_long() (there are some exceptions, like gcc, which use getopt_long_only() for historical reasons, and which therefore can spell long options with a single dash if there is no ambiguity, but use of getopt_long_only() is not recommended in new programs). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
