As a normal user, the script works. As root, however, even testing a file that is chmod 400 results in an incorrect test. I've tested with with bash from ports, and /bin/sh - same behavior. Linux fails in the same fashion, but Solaris works just fine (returns the expected result, which would be nothing.), regardless of shell. >How-To-Repeat: # if [ -w netsaintize ] > then > ls -l netsaintize > fi -r-------- 1 root wheel 0 Jun 1 21:02 netsaintize # >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
