Free command line reference software for linux

C++ Command Line Library provides a framework for handling command line options and arguments. Either variables (of any type) are set to values given at the command line. Or user defined functions are called with arguments (of any type) read from the command line.
It was developed and tested using kdevelop 2.1 and gcc 2.95.3 on SuSE Linux 7.3.x
Main features:
- Easy extraction of command line arguments
- Automatic conversion of command line arguments to any type (even user defined classes)
- Convenient handling of command line usage errors by exceptions
- Complete documentation
- And all this is absolutely free

Command Line Content Management System is my own command line content management system. Its not a dynamic cms, but a script that takes a source tree and creates a web site out of it.
The idea came to me when i was using m4 for my website to generate the HTML, but i did not like the idea that i was still typing HTML in my pages, even if it was simplified by using macros. I was updating a wiki page somewhere when it hit me: i wanted a command line system that was able to take wiki style input for page content. The result is clcms.
Its in beta state at the moment, mostly to try out some different approaches to various
challenges. But i thought id share it now, so if youre interested and might have some ideas on where to go from here, drop me a line (or a patch). At least it can build this site and the tutorial site, but anything more fancy will probably not work.
Its also a way for me to learn Python, so i might in my ignorance produce some weird constructs here and there. Please let me know, but be gentle.
Main features:
- Updates should be possible with a terminal and an editor
- Content is stored in a directory tree
- Adding pages (or items?) should be as easy as creating a new file and typing some lines in it.
- For default pages/items no config necessary
- No HTML, XML or anything alike for normal usage
- All pages have their binary content (images, download files) in the directory of the page itself
- All output is static, no generating on the fly
Usage:
After untarring the tarball, add < dir>/bin to your path or copy bin/clcms.py to a directory in your path.
You can now go to < dir>/examples/documentation and build the tutorial by running
clcms.py
Now wasnt that easy?
Point your browser to file://< dir>/examples/documentation/out/index.html and see the result of all your hard work.
If it did not work, its not your fault. Just remember that version number.
Enhancements:
- .page files can now contain content attributes.
- Filename extensions are removed and replaced by attribute lines in .page files.
- The page.meta file should now be called page.attr.
- The nomenu option had disappeared in a previous release, and has been put back.

Randomize Lines (rl) is a command-line tool that reads lines from an input file or stdin, randomizes the lines and outputs a specified number of lines. It does this with only a single pass over the input while trying to use as little memory as possible.
I wrote rl in my spare time mainly to be able to select a random audio file to play when my toast is done (script in combination with find and sleep). Another reason was to familiarize myself with autoconf and friends.
The most recent version of this page can be found at http://ch.tudelft.nl/~arthur/rl/.
Warning: rl is software in development. The command line options and default behavior may change between releases.
Another Warning: I have mostly lost interest in this project and am not planning on doing much development on it any more. I will however still accept patches and fix important bugs (this more or less contradicts the previous warning).
Enhancements:
- A dangerous example was removed from the manual page and was replaced by several benign ones.

WhileInterpreter is an interpreter for the WHILE programming language used for learning purpose.

WhileInterpreter has few constructs and easy semantics.

Command line interpreters allow users to issue various commands in a very efficient (and often terse) way. This requires the user to know the names of the commands and their parameters, and the syntax of the language that is interpreted. From the 1960s onwards, user interaction with computers was primarily by means of command line interfaces.

In the 1970s, researchers began to develop graphical user interfaces (GUIs)to provide an alternative user interface for computers, whereby commands were represented by pictorial operations, rather than as textual descriptions. Since they are easier to learn than command line interfaces, they have become the most common way of interacting with a computer.

However, command line interpreters remain widely used in conjunction with GUIs. For some complex tasks, the latter are less effective because of the large number of menus and dialog boxes presented and because of the innate difficulty of representing the underlying task graphically.

clive is a command line program that extracts videos from YouTube and Google Video websites. The project supports embedded video extraction, and can be used with ffmpeg to re-encode the extracted videos to different video formats (avi, mpeg, flv).

gimmage is an image viewer that is perfect for command line usage as it accepts directories and image filenames as arguments.

It has an in-application file browser that allows users to select and drag images and directories into the image viewing area in order to have them displayed.

cadaver is a command-line WebDAV client for Unix. cadaver project supports file download, upload, on-screen display, namespace operations (move/copy), collection creation and deletion, and locking operations.

cadaver is free software, distributed under the GNU GPL. Patches, bug reports, questions and so on should be sent to the mailing list (for which an archive is also available).
