This is invaluable for working on older locked down unix servers thank you. I have added an "i" before the final "g" to make it case insensitive. perl -pe 's/KEYWORD/\e[1;31;43m$&\e[0m/ig'

This is a great command but is easy to forget. The easy version is to instead pipe to egrep --color 'pattern|$'. So much easier to do and remember.
