Is this standardized somewhere? And since when do filenames starting with '-' need special handling all of the time? A lot of common tools do not behave that way, $ echo -v | grep -e -v -v $ { echo \#!/bin/sh; echo echo YES; } > -a $ chmod 755 -a $ sh -c -a YES $ Including sh(1) itself. But of course... $ rm -a rm: illegal option -- a usage: rm [-f | -i] [-dPRrvW] file ... unlink file $ rm -- -a $ Lotsa times '-' files do. -- Crist J.
