After a two year effort, I have released the first edition of "The Linux Command Line" in all of its 522 page glory!
I want to give special thanks to Mark Polesky for his extraordinary review and test of the book, as well as the rest of the review team: Jesse Becker, Tomasz Chrzczonowicz, Michael Levin, and Spence Miner.
Special thanks also go out to Karen Shotts for editing all of my so-called English.
To download the free PDF version of the book, go to https://sourceforge.net/projects/linuxcommand/files/ and get the file TLCL-09.12.pdf.
You may also purchase a printed version of the book in large, easy-to-read format (which is, in fact, very handy) by going to: http://www.lulu.com/content/paperback-book/the-linux-command-line/7594184
