Announcing my second e-book "Sed One-Liners Explained" - <AUTHOR> http://catonmat.net/blog/sed-book/

<comment><USER2> 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.

<comment><AUTHOR> Let me know if you pick it up and I'll send you an additional gift. :)

<comment><USER3> I got it.

EDIT: modified your tweet message, though.

<comment><AUTHOR> Sent you a present. Check your inbox. :)

<comment><USER3> Awesome- thanks- made my day. (glad you told me as it landed in spam bucket.)

<comment><AUTHOR> Craziness with the spam. I am glad you like the gift. :)

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..."

</comment><comment><USER5> Looks like a really well done and practical intro to sed - nice examples, nicely explained, and good depth. The PDF looks nice, too.

<comment><USER3> I agree. I use sed, but it's not a part of my 'top of the head' workflow. I have a few things I use regularly on a cheat sheet. Usually when I need to do something new I have to struggle a bit. Same goes for awk, actually.

The intro has a very nice conceptual feel to it. I look forward to going through the book.

</comment><comment><USER7> 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

<comment><USER8> I don't know about the book, but the posts it is based on (usefully linked to from the linked article, [http://www.catonmat.net/blog/sed-one-liners- explained-part-o...](http://www.catonmat.net/blog/sed-one-liners-explained- part-one/) if anyone wants a more direct link) are certainly worth a scan so it probably got a good few votes for that. I might have to consider purchasing the book myself.

<comment><AUTHOR> I'll send you a present if you buy a copy. :)</comment></comment></comment>
