Automatic creation of folders

A script posted in the forum by Cactus [1] and sent to me by Amir Inbar can be used to create all folders (in skel for futures users and in the existings users too :

# create skellaton for new users :

mkdir -p /etc/e-smith/skel/user/Maildir/{.LearnAsHam/{cur,new,tmp},.LearnAsSpam/{cur,new,tmp},.LearnInWL/{cur,new,tmp}}

# create folders for existing users :

pushd /home/e-smith/files/users/; \
for u in `ls | grep -v admin`; \
do \
mkdir -p $u/Maildir/.LearnAsHam/{cur,new,tmp}; \
chown -R $u:$u $u/Maildir/.LearnAsHam/; \
mkdir -p $u/Maildir/.LearnAsSpam/{cur,new,tmp}; \
chown -R $u:$u $u/Maildir/.LearnAsSpam/; \
mkdir -p $u/Maildir/.LearnInWL/{cur,new,tmp}; \
chown -R $u:$u $u/Maildir/.LearnInWL/; \
done; \
popd

Thanks to them.
