Best book for learning linux shell scripting? [closed]

I normally works on Windows machines but on some occasions I do switch to development on linux. And my most recent project will be written entirely on a certain linix platforms (not the standard Apache/MySQL/PHP setup). So I thought it would pay to learn to write some linux automation script now.

I can get around the system, start/stop services, compile/install stuffs fine. Those are probably basic drills for a programmer. But if, for example, I wanted to deploy a certain application automatically to a newly minted linux machine every month I'd love to know how to do it.

So if I wanted to learn serious linux shell scripting, what book should I be reading?

online: ABS

warning: this is a bash tutorial so there are bash-only syntaxes and I recommend you to not use them.

It is though a very good documentation

Learning the Bash Shell along with Classic Shell Scripting, followed by Bash Cookbook.

I would suggest charging through the first two books, without worrying too much about remembering it all. Reference them as you want to do something that you remember reading about but don't recall how to actually do. And come back to them a few a months later and learn new things from them.

Note, this is coming from the perspective of a linux admin, so I lean toward the niceties of bash over the more pure sh. It is only the rare script that I bother to actually make sh compatible. Also, I don't consider tcsh to be a legitimate scripting language.
