Re: umask^H^H^H^H^Hchmod a specific directory to be sticky

Greetings Mike!

 man chmod tells something about sticky directories:

STICKY DIRECTORIES
       When  the sticky bit is set on a directory, files in that directory may
       be unlinked or renamed only by root or their owner.  Without the sticky
       bit,  anyone able to write to the directory can delete or rename files.
       The sticky bit is commonly found on directories, such as /tmp, that are
       world-writable.

I gues that's just what you are looking for...

example:
mkdir /home/agroup
chgrp agroup /home/agroup
chmod -R 6774 /home/agroup

ls -lah /home/agroup
total 8.0K
drwsrwsr-x   2 root agroup 4.0K 2005-07-04 12:15 .
drwxr-xr-x  18 root root  4.0K 2005-07-18 09:42 ..

members of agroup are able to create files or directories in /home/agroup.
these files or directories still belong to the creator, but are editable by 
all members of agroup.


(and you don't even need umask in this case...)

thanks for your question
