Hi Chris:

# perl -ple 'if (m/(^OTHER.*)/) {print "expres63 auth required /usr/lib/security/pam_aix"}' file

Regards!

Hi (again) CHris:

If you still prefer 'awk', however, use:

# awk '{if ($1~/^OTHER/) {print "expres63 auth required /usr/lib/security/pam_aix"; print} else {print}}' file

Regards!

If you don't like JRF's perl and awk solutions, you can use sed:
sed -e '
/^OTHER/i\
expres63 auth required /usr/lib/security/pam_aix
' file
