Since v2.04, bash has allowed you to intelligently program and extend its standard completion behavior to achieve complex command lines with just a few keystrokes. Imagine typing ssh [Tab] and being able to complete on hosts from your ~/.ssh/known_hosts files. Or typing man 3 str [Tab] and getting a list of all string handling functions in the UNIX manual. mount system: [Tab] would complete on all exported file-systems from the host called system, while make [Tab] would complete on all targets in Makefile. This project was conceived to produce programmable completion routines for the most common Linux/UNIX commands, reducing the amount of typing sysadmins and programmers need to do on a daily basis.
smake is a highly portable 'make' program that makes commands up to date based on rules in Makefiles and on the timestamps of the related files. It implements a complete superset of the features of the classical POSIX/Unix make program. It warns about typical misuse of dynamic macros that prevent portability of makefiles. Its automake features allow you to run scripts to automatically create rules for unknown platforms.
The GNU Autoconf Archive is a collection of more than 450 macros for GNU Autoconf. They can be re-used without imposing any restrictions on the licensing of the generated configure script. In particular, it is possible to use them in configure scripts that are meant for non-free software.
DIY Zoning is a set of tools and instructions for controlling a state-of-the-art HVAC (Heating, Ventilation, and Air Conditioning) system. It covers airflow balancing, temperature control and zoning, energy conservation measures, remote access, 1-wire devices, and home automation.
docx2txt is a tool that attempts to generate equivalent (ASCII) text files from Microsoft .docx documents, preserving some formatting and document information (which MS text conversion drops) along with appropriate character conversions for a good (ASCII) text experience. It is a platform independent solution consisting of (core) Perl and (wrapper) Unix/Windows shell scripts and a configuration file to control the output text appearance to fair extent. It can very conveniently be used to build a Web based docx document conversion service. Some Makefiles and Windows batch files are provided for easy installation of the scripts. With unzippers like CakeCmd that can deal with corrupt Zip archives, this tool can extract text from corrupt docx documents in many cases, where MS word processor fails to even open them.
Vee is a command-line blog tool that is very portable across Unix systems. It provides an interactive as well as a batch interface to maintain a log of entries. Formatting is done using a module architecture that allows a high degree of customization. There are minimal flags and no set up is required.
RefSense is a set of command line tools for accessing PubMed. They allow you to search PubMed from a terminal (such as xterm), retrieve Web pages or PDFs, find related articles, convert to BibTeX, and much more by only using a keyboard. It also provides convenient word completion on titles, author names, etc.
