Sorry, but this isn't anything new. Even 10 years ago, POSIX called options like `-1' (and `-666' :-) obsolescent, and tools like getopt don't treat them the same way as regular options. Actually, it's all in the interests of consistency: for example, options like comm's -1, -2, and -3 are ok, but options like head's -N (where N is a positive integer) are not. _______________________________________________ Bug-textutils mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-textutils
