System: FreeBSD linwhf.opal.com 6.0-CURRENT FreeBSD 6.0-CURRENT #62: Tue Sep 28 15:27:07 EDT 2004 jr@linwhf.opal.com:/usr/src-current/sys/i386/compile/LINWHF i386
>Description:
When grep(1) is invoked as bzegrep or bzfgrep, it fails to
detect that it should use the egrep or fgrep matcher and behaves
as grep. Use of the -E or -F flags works, i.e., it is the
parsing of argv[0] that's broke.
>How-To-Repeat:
$ bzegrep '^(root|toor):' /etc/passwd
$
compare with:
$ bzegrep -E '^(root|toor):' /etc/passwd
root:*:0:0:Charlie &:/root:/bin/csh
toor:*:0:0:Bourne-again Superuser:/root:
