Well, I'm not doing that, so it's not likely the problem. :) It's related, though. > I always use the '=' format to connect the option to the argument > (e.g. --exclude=/proc/*).

Well, that, and figuring out that I can't quote the filenames used for the --exclude-from argument. What I needed to do was remove the double quotes. Quoting arguments is standard practice in my shell scripts (and most, AFAIK). That way, if there's a space or something in the thing being specified, everything's cool. It appears, though, that rsync somehow gets those quotes (I thought bash was supposed to take them out), and it's literally trying to match "/proc/*", quotes and all. Argh. So, I can take the quotes out, and use = to connect the terms to the argument. That's fine, as I don't have any spaces in filenames anyway. However, what happens if I want to exclude a file with spaces, or similar? One of these machines is a file server for Win32 and MacOS X clients, and those users like spaces. What about other special shell chars? I'd *like* for my script to not just randomly break if shell meta chars happen to appear in a filename somehow. I guess this turns into a question for the bash developes - though I'm up to date with that, as well. Here's what I do, basically: RSYNC="/usr/bin/rsync" ARGS="-a -b -c -d -etc" EXCLUDES=`mount | perl -ane'if ($F[4] !~ /^ext[23]) print "--exclude=\"$F[2]\" "'` $RSYNC $ARGS $EXCLUDES $SRC $DEST Oh, I see. That made it clear. The quotes are inside the $EXCLUDES var, and are therefore not seen by the shell. If I had just typed in what was posted earlier, it *would* have worked. The problem is that the quotes aren't handled after the variables are interpreted - they're passed as part of the argument, so rsync sees them as part of the filename. OK, that's cool, since it means I shouldn't have to worry about the metachars anyway. Back to shell-scripting 101 for me, eh? Maybe 201? :) Thanks for leading me in the right direction, all who did so (however inadvertently it may have been). --Danny -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
