The host is at secure site. Can rsync use a secure socket like ssh? I guessed that it couldn't but I'll admit I didn't look into it. -- Gary On Thu, 19 Jul 2001, Charles R .

Sounds like a job for rsync. It can synchronize files, links, devices, directories, owners, groups, and permissions. It will only transfer the "differences" over the network, making it extremely fast. These options should do what you want (but I haven't tested this): -p, --perms This option causes rsync to update the remote permissions to be the same as the local permissions. --existing This tells rsync not to create any new files - only update files that already exist on the destination. I'm not sure if rsync can synchronize JUST permissions, and not file contents as well. It might be worth looking into, though.

Big plus. :-) Thanks Charles. -- Gary

I figured you'd use the version without the -t like this: stat file | grep "Access: (" | cut -d\( -f2 | cut -d/ -f1 It works with directories too.

My script was going to be something along the lines of awk/if-then-else-fi/echo. :-) Can this be tweaked for directories also? You lost me after tr. -- Gary

Some shell hackery: set -- $(ls -l foo) OCTMODE=$(echo "ibase=2;obase=8;$(echo $1 | tr -- '-drlwcxb' '0 1 1 1 ')" | bc) Season to taste. Tweak for hex to octal conversion. ccb -- Charles C.

Check out the 'stat' command and 'stat -t'.

Permissions on a file

by Gary J. Hanley

Hello all, Does anyone know how I would go about listing the permissions of a file in octal format instead of symbolic? I need to pass that value to a script somehow, and although I could write a script to do that I didn't want to waste my time if there was already a command to do that. Thanks! -- Gary
