The Advanced Bash Scripting Guide is both a reference and a tutorial on shell scripting. This comprehensive book, the equivalent of 1,032 print pages, covers almost every aspect of shell scripting. It contains 382 profusely commented illustrative examples, a number of tables, and a cross-linked index/glossary. Not just a shell scripting tutorial, this book also provides an introduction to basic programming techniques, such as sorting and recursion. Included scripts are the Game of Life, a Perquackey variant, a Morse code trainer, and an implementation of the Gronsfeld Cipher. This book is suited for both individual study and classroom use. It covers Bash, up to and including version 4.2. Note that users of miniaturized single-board computers running Linux, such as the Raspberry Pi and the Beagle Bone, would find this Guide useful for learning and running Bash scripts to explore and expand the capabilities of these small, but powerful machines.

Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attackers' IP addresses into the ipfw2 table, effectively blocking them. Addresses are automatically removed from the table after specified amount of time. Bruteblock uses regular expressions to parse logs, which gives it enough flexibility to be used with almost any network service. Bruteblock doesn't use any external programs and works with ipfw2 tables via the raw sockets API.
