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. HTH Neil Youngman
