Hi all, If it's a festive time of year where you are then I hope you're enjoying it.
First of all, apologies if this is not the correct list for this query. Perhaps you could suggest where else I should go. I have a 3-line script; foo: #!/bin/bash id -u # EUID id -u -r # `real' UID Here's it's directory listing: -rwsrwxr-- 1 root adm 1317 Dec 27 16:18 foo I set these permissions with the command: $ sudo chmod 4774 foo Here's what I get if I run foo as myself (UID 1000): $ ./foo 1000 1000 Surely this should be: $ ./foo 0 1000 ... or am I missing the point somehow? I started to investigate the behaviour of the set-user-id bit because of another problem I've been experiencing for some time: A cron.daily script handles mandb. I elected to install it with the set-user-id bit set, as you can see: /usr/lib/man-db: used 220 available 573264 drwxr-xr-x 2 root root 4096 Oct 16 15:13 . drwxr-xr-x 116 root root 24576 Dec 14 11:49 .. -rwsr-xr-x 1 man root 86932 Sep 21 13:23 man -rwsr-xr-x 1 man root 96808 Sep 21 13:23 mandb Every day I receive the same message in my inbox: /etc/cron.daily/man-db script: mandb: can't create a temporary filename: Permission denied mandb is a binary executable file so I have no idea where it is trying to create the temporary file, but it certianly shouldn't have any trouble creating it in /tmp: drwxrwxr-x 13 root root 4096 Dec 27 16:50 /tmp Any help with either of these issues is very much appreciated. sdt -- GNU bash, version 3.1.0(1)-release (i486-pc-linux-gnu) Copyright (C) 2005 Free Software Foundation, Inc. _______________________________________________ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash
