A review of From Bash to Z Shell has made it onto slashdot: http://books.slashdot.org/article.pl?sid=05/04/13/203225

Along with two other authors, I have written the book From Bash to Z Shell: Conquering the Command Line. It was published a couple of months ago and is now widely available. The book explains how to get the most out of the Unix command-line and pays particular attention to the bash and zsh shells. For more information, see http://www.apress.com/book/bookDisplay.html?bID=361. Or, go to amazon to buy the book and read reviews:
