I have Linux in a Nutshell 4th edition. I found that a fair amount of the information is no longer valid. I've managed without it because of the extensive online information (both on the system and on the WEB) and my extensive experience with Unix.
I'd like to get a new edition that is up to date. However, the last edition available is already 3 years old. The book has gone through 6 editions 1997, 1999, 2000, 2003, 2005, 2009. the average time between editions is 2 years. Linux evolves so much in that time (i.e. 2 years) that any published text older than that is virtually obsolete. When will the new edition of Linux in a Nutshell be available?
There has not been a 7th edition of Linux in a Nutshell that has been announced at this time. However, we do have a few newer books on the subject that have been released recently.
Perhaps these books would be useful to you?:
"The Linux Command Line "
"The Linux Pocket Guide, 2nd ed:"
