Info

Advanced Bash−Scripting Guide David Medinets, Unix Shell Programming Tools, McGraw−Hill, 1999, 0070397333. Good info on shell scripting, with examples, and a short intro to Tcl and Perl. * Cameron Newham and Bill Rosenblatt, Learning the Bash Shell, 2nd edition, O'Reilly and Associates, 1998, 1−56592−347−2. This is a valiant effort at a decent shell primer, but somewhat deficient in coverage on programming topics and lacking sufficient examples. * Anatole Olczak, Bourne Shell Quick Reference Guide, ASP, Inc., 1991, 093573922X. A very handy pocket reference, despite lacking coverage of Bash−specific features. * Jerry Peek, Tim O'Reilly, and Mike Loukides, Unix Power Tools, 2nd edition, O'Reilly and Associates, Random House, 1997, 1−56592−260−3. Contains a couple of sections of very informative in−depth articles on shell programming, but falls short of being a tutorial. It reproduces much of the regular expressions tutorial from the Dougherty and Robbins book, above. * Clifford Pickover, Computers, Pattern, Chaos, and Beauty, St. Martin's Press, 1990, 0−312−04123−3. A treasure trove of ideas and recipes for computer−based exploration of mathematical oddities. * George Polya, How To Solve It, Princeton University Press, 1973, 0−691−02356−5. The classic tutorial on problem solving methods (i.e., algorithms). * Arnold Robbins, Bash Reference Card, SSC, 1998, 1−58731−010−5. Excellent Bash pocket reference (don't leave home without it). A bargain at $4.95, but also available for free download on−line in pdf format. Bibliography 364
Advanced Bash−Scripting Guide * Arnold Robbins, Effective Awk Programming, Free Software Foundation / O'Reilly and Associates, 2000, 1−882114−26−4. The absolute best awk tutorial and reference. The free electronic version of this book is part of the awk documentation, and printed copies of the latest version are available from O'Reilly and Associates. This book has served as an inspiration for the author of this document. * Bill Rosenblatt, Learning the Korn Shell, O'Reilly and Associates, 1993, 1−56592−054−6. This well−written book contains some excellent pointers on shell scripting. * Paul Sheer, LINUX: Rute User's Tutorial and Exposition, 1st edition, , 2002, 0−13−033351−4. Very detailed and readable introduction to Linux system administration. The book is available in print, or on−line. * Ellen Siever and the staff of O'Reilly and Associates, Linux in a Nutshell, 2nd edition, O'Reilly and Associates, 1999, 1−56592−585−8. The all−around best Linux command reference, even has a Bash section. * The UNIX CD Bookshelf, 3rd edition, O'Reilly and Associates, 2003, 0−596−00392−7. An array of seven UNIX books on CD ROM, including UNIX Power Tools, Sed and Awk, and Learning the Korn Shell. A complete set of all the UNIX references and tutorials you would ever need at about $130. Buy this one, even if it means going into debt and not paying the rent. * The O'Reilly books on Perl. (Actually, any O'Reilly books.) −−− Bibliography 365
