Hi Neil

Thanks. I spoke to my guru Bero and he gave me this line.

 sed -i -e 's|arklinux|NewUser1,NewUser2,NewUser3|g' /etc/pam.d/*

It works great. I'm making note of your line as it creates instant
backups. I always tar.bz2 everything before I alter it. So the PAM
directory has been backed up quite tidy.

Thank you for your help, it's greatly appreciated.
