Hi

I know this isn't exactly a Trinity-centric question but it will eventually apply to it as I switch from KDE3 to TDE. So please bare with me.

Does anyone have any experience with SED and PAM? I need to replace the default admin user (arklinux) with 2 new users.

I normally use sed -i -e 's,arklinux,NewUser,g' /etc/pam.d/* to change the admin user in PAM.

How to a pose it so it adds two more users?

Something like this?

$ sed -i.bak -e 's/(.*)arklinux(.*)/\1NewUser1\2\ \1NewUser2\2/' /etc/pam.d/*

The obvious limitation on that is it will probably only work where arklinux

appears once on a line. Multiple occurrences would need a bit more thought.

Test carefully before use and note the -i.bak to backup the originals in case of mistakes.

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.

Kate
