mbuffer is a tool for buffering data streams. It is also a replacement for buffer with additional functionality: - multi-target network output - on the fly hash calculation - display of I/O speed - optional use of memory mapped I/O for huge buffers - multithreaded instead of sharedmemory ipc - multi volume support - autoloader support - networking support - command-line options compatible to buffer

Prints to stdout a series of numbers from `start' to `end', with optional increment and zero-padded field width. Hex (-x) or octal (-o) output formats are available. Negative numbers are allowed, and a negative `increment' does the expected thing.

mmv is a program to move/copy/append/link multiple files according to a set of wildcard patterns. This multiple action is performed safely, i.e. without any unexpected deletion of files due to collisions of target names with existing filenames or with other target names.

mtail is a small tail workalike that performs output coloring using ansi escape sequences (although the sequences are overridable, so you could cause it to output something else, e.g. html font tags, if you really wanted to). mtail is written in python, is fairly small, and should be relatively platform-independent. It has a config file that can contain an arbitrary number of entries, each of which has a series of regular expressions to indicate which files to color according to which entry. for each entry, the config file specifies a coloring scheme using regular expressions and, optionally, filters to apply to each line before coloring (for example, to strip out extra info, etc.). the config file also may override the predefined colors and the escape sequences (or whatever) actually used to perform the coloring.

OSSP uuid is a ISO-C and Perl application programming interface (API) and corresponding command line interface (CLI) for the generation of DCE 1.1 and ISO/IEC 11578:1996 compliant Universally Unique Identifiers (UUID). It supports DCE 1.1 variant UUIDs of version 1 (time and node based), version 3 (name based, MD5), version 4 (random number based) and version 5 (name based, SHA-1).

pfm is a terminal (curses)-based file manager written in Perl, based on the PFM.COM for MS-DOS (originally by Paul Culley and Henk de Heer). Permission to use the original name was kindly granted by the original authors. Some of its features: * Commands are invoked with only one or two keypresses * Colored filenames according to extension or type * Support for executing user-defined commands (including wildcards) with only two keystrokes * A single-file and multiple-file mode * Multilevel sorting * Use of oldmarks and newmarks for executing multiple commands on the same group of files * Supports bookmarks for directories * Highly configurable through its config file * Supports commandline history and completion through use of the GNU readline library * Integration with versioning tools like Subversion, CVS, Bazaar, Mercurial, and Git

Acme::ButFirst allows you to execute a block of code, but first do something else. Perfect for when you wish to add to the start of a long block of code, but don't have the energy to scroll upwards in your editor. Acme::ButFirst recognises both butfirst and but first as keywords. Usage of Acme::ButFirst is lexically scoped. ButFirstification can be explicitly disabled by using no Acme::ButFirst.

Array::Compare is a Perl module which allows you to compare two arrays. It has a number of features which allow you to control the way that the arrays are compared: * white space in array elements can be significant or ignored. * particular columns in the arrays can be ignored. Additionally you can get a simple true/false return value or the number of columns which differ or an array containing the indexes of the differing columns. Seamus Venasse <svenasse@polaris.ca>

This module do diff two arrays, and return added and deleted arrays. It's simple usage of Algorithm::Diff.

Markov bots like Hailo and AI::MegaHAL are fun. But to get them working you either need to train them on existing training material or make your own. Bot::Training provides a pluggable way to install already existing training files via the CPAN. Bot::Training also comes with a command-line interface called bot-training.
