This command must be used after you create the directory, and before you put any files in it.
To change the group for a directory, use the command setweb directory-name:
stealth% pwd /stealth/users/ariel/Mail stealth% ls -ldg stuff drwxr-x--- 2 ariel staff 512 Jul 28 15:34 stuff stealth% setweb stuff stealth% ls -ldg stuff drwxr-x--- 2 ariel www 512 Jul 28 15:34 stuff
Now you can move files into the directory or create new files, and they will all have the correct group associated with them:
stealth% cd stuff stealth% cat > junk here's some junk for the junk file [^D here] stealth% ls -lg total 1 -rw-r--r-- 1 ariel www 35 Jul 28 16:18 junk
