How to highlight keywords when using tail

Have you ever been tailing a log file looking for a specific keyword or phrase? Maybe you’re tailing an Exim log watching for an email, or an Apache log file for a specific request. Wouldn’t it be really great if you could highlight the keyword or phrase? Here’s How to highlight keywords when using tail.

The “\e…/g” section can be replaced by some semicolon-separated integers, with the meaning:

0 : all attributes off
1 : bold
31 : foreground red
43 : background yellow

“keyword”, of course, can be any perl regular expression:

(foo|bar) highlight the strings foo and bar
\b((foo|bar)\b highlight the words foo and bar
.\b((foo|bar)\b. highlight the whole line that contains the words foo or bar
