group sticky bits (confused on how, clear on concept)

bpk · 02-03-2005, 05:56 PM

Lots of users are writing from a directory, ie; /data/scans.

I'd like for every file in that directory to be owned by whomever wrote it, I don't care. But I'd like for every file to have the same group, ie; staff.

Whats the chmod command for that? I get so confused how to apply these things and the HOWTO's are confusing (to me).

Have a much better time learning through example.

use chgrp to change group properties, not chmod.

e.g. as root, cd to directory and chmod all files

su
..password
cd [dir]
chgrp [group] *

of course that will only work if you are root. you could add the script to cron config to make it run every hour or whatever?

Or just make the primary group of all users who write
to the directory staff ... saves you all the other hassles.

Maybe im not explaining this correctly.

I'd like to change the sticky bit, so that when a file gets written to the directory, the group ownership will foreceully become whatever it's parent is.

Lets say Joe:Joe upload a file. The file would be owned by Joe and Group owned by Staff (not joe).

Understand?

There is no unix/linux way of "inheriting" the
group ownership from the parent directory.

chmod 1775 /data/scans
chown root:staff /data/scans
usermod -g staff joe

i think this should work:

chgrp [group] ./
chmod g+s ./
