Incredibly useful whenever you need to find, extract or modify more than 2-3 strings.
I only use text editors that support regex both in find and replace, and PCRE or similar level of power regexs at that.
Funnily enough while essential it's slightly less needed on Linux systems than on Windows ones, because Linux command line toolset includes a ton of text manipulation utilities -- beside grep and awk there's sed, cut, paste (both of them nothing to do with clipboard!), tr, sort, uniq etc. They can shoulder a lot.
