The Aardvark Shell Utils is a collection of three utilities designed to aid the user when working with shell scripts or from the command line. All three accept input on the command line or from standard input, and thus they can be piped with other commands. All commands come with their own man page. Included are realpath, filebase, and fileext.
acoc is a regular-expression based colour formatter for programs that display output on the command-line. It works as a wrapper around the target program, executing it and capturing the stdout stream. Optionally, stderr can be redirected to stdout, so that it, too, can be manipulated. acoc then applies matching rules to patterns in the output and applies colours to those matches.
Augeas is a configuration API and editing tool. It parses common configuration files like /etc/hosts or /etc/grub.conf in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native configuration files.
Chit is a template based generator for textual data, such as program code, configuration data, or anything else you can imagine. It gathers its input from data in a relational database. This means that the output text is generated from a template according to a given SQL statement. This tool's original purpose was to generate configuration files for Nagios from a local PostgreSQL database.
Common Configuration Parser (CCP) is a program that reads configuration files and upgrades them. It takes an oldfile (typically the configuration file currently in use) and a newfile (typically the default new configuration file) and optionally a template (a file that describes how the generated configuration file should look) and merges the files into one, creating a new configuration file that has the changes made to the old file in addition to the new options included in the new file. It is completely independent of the program that created the configuration file, and can be used for many different purposes such as merging changes between an old user-edited configuration file and a .rpmnew file generated by RPM during upgrades.
Geolizer is a patch for Webalizer that uses the GeoIP library to generate faster and more reliable geographic statistics than the default DNS suffix method. It is recommended that DNS reversal be disabled on your HTTP server for improved performance and more accurate statistics. It also supports country flag pictures, can be compiled under MinGW/MSYS, and features a human-readable transfer size display.
John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. On top of this, lots of other hashes and ciphers are added in the community-enhanced version (-jumbo), and some are added in John the Ripper Pro.
