From e3bab0cc706880c22f2b205e7abad9d8c0227071 Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Thu, 29 Jan 2015 11:23:01 +0100 Subject: startx: Don't use GNU expr extensions Use the ':' operator instead of "match" and avoid the use of "\+". Both constructions aren't specified by POSIX and not supported in BSD expr. Also drop the '^' from the regular expressions as it is implicit and POSIX leaves its behaviour undefined.
