I gotta say, I really enjoyed skimming through this, and saving it for future reference. I can already tell there are some basic things that I should've memorized with all the one liners I've used, but because most were cobbled together for the immediate task (and many online forum searches assume a lot of prior knowledge), so t this presentation, and cookbook style references really help me hold the practical benefits in memory alot longer, so thanks again!
if you are interested in text processing in general, do check the other chapters for grep/sed/perl/sort/paste/pr/etc
I learned a lot writing them up and marvel at the speed and functionality provided by these tools.. for many cases, it is lot easier to write a bash script combining these tools than to write a Perl/Python/Ruby script..
