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.
