No, you're missing one other key point of POSIX: http://www.opengroup.org/onlinepubs/9699919799/utilities/V3_chap01.html Section 1.4, OPTIONS: Default Behavior: When this section is listed as "None.", it means that the implementation need not support any options. Standard utilities that do not accept options, but that do accept operands, shall recognize "--" as a first argument to be discarded. The requirement for recognizing "--" is because conforming applications need a way to shield their operands from any arbitrary options that the implementation may provide as an extension. For example, if the standard utility foo is listed as taking no options, and the application needed to give it a pathname with a leading <hyphen>, it could safely do it as: foo -- -myfile and avoid any problems with -m used as an extension. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
