Handbook of Text manipulation on Unix

Thanks for this! I really like these kinds of summaries, because while I love grep and cut and wc and perl, there are commands in here I really haven't heard of.

Plus I enjoy stringing together one-off filters longer than my arm.

Related to this, pyp is worth taking a look at if you're interested in doing manipulation using python's libraries, but on the command line:

Also take a look at my 3 e-books on awk, sed and perl: http://www.catonmat.net/books/

So sad that the writer lets himself down in the first line.

I like how it's laid out from the most specific tools that are easy to understand and eventually leads to the pocketknives of sed and awk that beginners might not need until they've exhausted the potential of the previous commands.
