Another bored expert desperate for a modicum of excitement ? You have absolutely no prima facie evidence to support your assertion. I refer you to my posting dated Mon, 09 Feb 2015 22:10:35 +0000 which includes, inter alia:- "Keith neither of us know whether or not the Russian man obtained his PDF copy of the book lawfully. In my book-publishing opinion, the PDF appears to have originated from the book's publisher, so the original source must have been *the* official source. Hence the book, in the PDF version, must have been written by the official authors. "The existence of an alleged unpaid-for copy on a foreign web site can not, in any sense whatsoever, denigrate, diminish nor deprecate the official authors distinguished achievement. "There are poor people all around the world who enjoy computers including Linux and whom would benefit from learning more about Linux. Some who can read English sufficiently proficiently to benefit from the book's text, may be too poor to afford the, to them in their country, "exorbitant" Western price for an "official" copy. Some publishers recognise this reality and sell in third-world countries at a small fraction of the "Western" price. In those circumstances selling PDFs for an extremely low price may be the source of this particular PDF especially as hardbacks and paperbacks could never economically be sold as low as a very low cost "official" PDF copy." FACT: Valeri's recommendation is, in my opinion, a useful source of basic knowledge benefiting Centos users regardless whether that book in printed on paper or is a virtual or an electronic "book" (i.e. PDF). ANOTHER FACT: Linux Programmer's Reference, Petersen, Osborne McGraw-Hill 1998 - ISBN 0-07-882587-3, which I obtained on 27 October 2000, is also a good good source of useful information. I've started re-reading the 71 pages on BASH. I never knew the first character on the first line could be a space. -- Regards, Paul. England, EU. Je suis Charlie.
