Sounds like Linux gets the nod. I took a look at the Practical Linux book's TOC and compared it to the more recent The Linux Command Line (NoStarch Press) a coworker loaned me. I believe they're comparable in content and I have a better shot of making it all the way through the LCL (half the size of PL).
I was a little hesitant to get a pentesting book since I was afraid it would cover a lot of material I already saw in the CEH, in addition to material I probably wouldn't see in PWB (e.g. social engineering, wireless, and the ubiquitous warchalking
Anyway, thanks for the input. I gotta admit, I was surprised there wasn't more support for Coding For Pentesters as, on the surface at least, it looked to me like the perfect prereq for the coding requirement.
