Open Source Command Line Tools

CRGREP searches for matching text in databases, various document formats, archives and other difficult to access resources. A command line tool for name and content text matching in database tables, plain files, MS Office documents, PDF, archives, MP3 audio, image meta-data, scanned documents, maven dependencies and web resources. CRGREP will search resources within resources of any arbitrary combination or depth, so text within a document within a zip archive, and so on. Here you will find binary downloads and discussion (https://sourceforge.net/p/crgrep/discussion/) . The actual development and issue tracking can be found here: https://bitbucket.org/cryanfuse/crgrep

xjobs has a command line interface similar to xargs to start processes, but runs processes in parallel and provides enhanced concepts for I/O redirection.

An implementation of Dantzig-Wolfe decomposition built upon the GNU Linear Programming Kit. This is a command line tool for solving properly decomposed linear programs. There are several examples and some documentation to guide the use of this solver. Forked over to GitHub (see link).

Another SiteCOPY (ascopy) is a command-line tool to maintain remote copies of websites and is completely written in Bash, so no compilation required and very portable.

analyzematrix is a command line tool for learning detailed information about a matrix including its inverse, determinant, eigenvalues, eigenvectors, and singular value decomposition.

The M6811 Code-Seeking Disassembler is a command-line tool that lets you enter known starting vectors for a given code image for the 6811 micro. It will disassemble the code and follow through branches to assist in the separation of code and data. Its companion Fuzzy Function Analyzer uses DNA Sequence Alignment Algorithms to locate similar code in multiple binaries, facilitating reverse-engineering. Originally written to analyze code from GM automotive engine controllers, but is useful anywhere a 6811 micro is being used. Version 1.0 was written in Borland Pascal in April 1996, and updated to v1.2 in June 1999. It was later rewritten to C++ in July 1999 through Jan 2000. While it's been freely available since its creation, it's being released here as an open-source project so the world can better use it as it sees fit. Version 2.0 is completely reworked in 2014 to compile and run with GCC and STL to make it fully portable and accessible to all computer platforms.

THIS PROJECT MIGRATED TO https://gitlab.com/mwetoolkit/mwetoolkit3/ The Multiword Expressions toolkit aids in the automatic identification and extraction of multiword units in running text. These include idioms (kick the bucket), noun compounds (cable car), phrasal verbs (take off, give up), etc. Even though it focuses on multiword expresisons, the framework is quite complete and can also be useful in any corpus-based study in computational linguistics. The mwetoolkit can be applied to virtually any text collection, language, and MWE type. It is a command-line tool written mostly in Python. Its development started in 2010 as a PhD thesis but the project keeps active (see the SVN logs). Up-to-date documentation and details about the tool can be found on the mwetoolkit website: http://mwetoolkit.sourceforge.net/

a nice, small command line tool useful as a stopwatch.

This command line tool for Linux allows to dump stdout of any application into rotating files, which either do have a fixed size or provide storage for a fixed time window.
