           Summary: --exclude options work from commandline but not in
                    script
           Product: rsync
           Version: 2.6.4
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P3
         Component: core

Greetings!  Thank you for such a wonderful tool in rsync.

I am trying to use rsync to back up one filesystem tree to another on the same
disk.  The catch is that the destination tree is mounted under the source tree.
 To prevent the backup from getting a copy of itself, I have tried to use the
--exclude option, but to no avail.  The general procedure for my script is to cd
to the destinateion directory (in this case: /mnt/backup) and rsync the source
directory (in this case: /) to the destination directory.  Here's the
command
that gets run:

/usr/bin/rsync -v --progress --delete --stats --exclude='/proc/'
--exclude='/sys/' --exclude='/mnt/sysbackup/' -aS / .

I want to exclude the /sys, /proc, and /mnt/sysbackup directories and
*everything* underneath them from being backed up to the /mnt/sysbackup
directory.  The kicker is that if I run that command manually like so:

( cd /mnt/sysbackup; /usr/bin/rsync -v --progress --delete --stats
--exclude='/proc/' --exclude='/sys/'
--exclude='/mnt/sysbackup/' -aS / . )

it works fine.  When the exact same rsync command is run from within the script
(following the cd /mnt/sysbackup command), I get a /mnt/sysbackup/mnt/sysbackup
directory with *everything* under the /mnt/sysbackup directory duplicated.  I
also get /mnt/sysbackup/sys and /mnt/sysbackup/proc directories complete with
data in them.

Cheers!
