Use CONFIG_EXTRA_COMPAT=y. I just tested, with this option off I am getting "Invalid range end", with it on I dont. This options makes grep use GNU regex matching. I bet GNU grep uses GNU regex matching routines, not POSIX. The differense has to be only on C API level - GNU regex can match NULs, POSIX cannot. But apparently in reality the differences run deeper. -- vda _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
