How do I create a directory in every home dir?

[Santiago del Roi]

I've got a Linux mail server running with about 100 users. I'm adding some Anti-Spam software and I want to have it put the spam into a subfolder of the Maildir folder in each user's home directory. Now I've implemented this in my own account and it works fine. My questions now is how can I add this Spam folder to every existing user's homedir with correct ownership and write permissions? I've already added it to the /etc/skel folder but that won't help my existing users.

Try something like this:

#!/bin/bash

for  home in `awk -F: '{print $6}' /etc/passwd`
do
   [ -d "$home" ] || continue
   [ -r "$home" ] || continue
   (cd $home; tar xvf archive_to_deploy_to_users.tar)
done
exit 0

I use something similar to convert a bunch of .wav files in an arbitrary directory to .flac.

Thanx. That worked.
