Announcing my second e-book "Sed One-Liners Explained"

The book looks good. I might pick it up. I think sed is one of those hidden power tools that everyone that works in the shell should pick up skills with. It's really helpful in some situations.

Nice. Finally motivated me to get the awk one as well. While you have mentioned doing a perl one next, I would also suggest considering something like "all the misc unix tools you never remember to use" (e.g. seq, col, cut, etc.) There is a bit of overlap among these tools to sed/awk/etc but this would probably lead to a nice "here is how you can do this in awk/sed, and here are the two args that make this command do the same job..."

Looks like a really well done and practical intro to sed - nice examples, nicely explained, and good depth. The PDF looks nice, too.

Tetris in sed? Awesome!

It it just me or does it seem like this article has been promoted with some kind of voting ring?

I don't know, it just seems strange to me for the HN community to upvote like this :S

EDIT: Ok, it sounds like they were completely legitimate upvotes. Nevermind then
