Free command line parameter software for linux

Command Line WRAPper is a tool that provides an easy way to build and run commands from input lines, avoiding the use of shell script. It is similar to xargs.

clwrap can make great things with the locate command, and is low resource intensive. It can also do some not-quite-fun works like multiple configure/make/make install after a fresh system installation. In practice, you have to generate a list of files/directories you want to manage, clwrap takes it in standard input and apply the command you want to apply for each files (lines) in input.

But you can do much more, in fact, its up to you to find how to use it ;).

examples:

- copying several files into one specific directory:

locate myfiles | clwrap -e cp {} mydir/

- renaming several files:

ls -1 ultra*
| clwrap -e "echo -n mv -v {}" -e "echo {} | sed s/ultra/ /"
| clwrap -e {}

- running a specific line in the shell history:

history | grep "482" | head -n 1 | sed s/ *[0-9]* *// | clwrap -v -e {}


- try all tv norms and frequency tables possible combinations with scantv:

cat norm
| clwrap -e "cat freq | clwrap -e echo scantv -n {} -f {}"
| clwrap -e {} > file 2>&1

- reformat source code, after a backup of course:

ls -1 | clwrap -e "cp {} {}.orig && flip -u {} && cat {}
| sed s/^[ t]*$//;/^$/d
| indent -kr -bad -bap -bbb -sob -i8 -l100 {} -o {}.tmp
&& mv {} tmp && mv {}.tmp {}"

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

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.

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.

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).

Digital Camera Protocol is another command-line utility for DC21x cameras, this one looks and works just like "ftp" command. Not written by me, but uses some of my low-level Kodak code from digicam.

gmodconfig aims to provide a simple way for end-users to download, install, configure and update Linux kernel modules, in the language of their choosing, through an easy-to-use graphic interface.
gmodconfig is a Gnome application which allows Linux users to:
Main features:
- configure kernel modules parameters, in their native language (if such translations exist),
- check for new versions of kernel modules, as well as download, build and install those
- access kernel modules informations (license, authors, link to website)
Its mainly aimed at inexperienced Linux users, however even long time Linux users might find it useful!
A user might have to set or modify kernel modules parameters in order to get a device driver to work properly on his/her system. One way to assign values to kernel modules parameters is to edit the /etc/modules.conf file. Another way is to load the kernel modules manually on the command line and pass them parameter values at that time. Neither of which is convenient or doable by non-experienced users.
Non-English speakers might find configuring kernel modules parameters even more difficult since informations on parameters returned by modinfo are only available in English.
Another obstacle is that the set of valid parameters values is not always apparent in modinfos output. For example an "on/off" type of parameter will be documented as being an integer, since boolean is not a supported type. Or an integer parameter whose valid values are 0, 1 and 2 might be documented as integer instead of a [0,2] array. This might make it difficult to users to figure out which values can be assigned to a parameter.
Checking for updates, download, build and install a new version of a Linux kernel module is not an easy task for newbie Linux users. There ought to be an easy and automated way to do all this.
gmodconfig solves these problems by reading accurate parameter types, parameter descriptions translations, and extra informations such as a link to the module authors website from XML files, that are released along with gmodconfig. Using this data as well as modinfos output, gmodconfig is able to dynamically build a user-friendly graphic interface which presents the list of parameters that each kernel modules supports.
Boolean parameters can be toggled on and off with a check box. Array parameters, that is, parameters whose valid values fall between a "min" and a "max" values are represented by a pulldown list. Other types of parameters are simple text entry fields.
Users can navigate through the available modules or search a module by name, change parameters settings at will, and will be able (in a future release) to "give it a try" by (re)loading modules, all from the graphic interface. Unsaved modifications can be cancelled at any time, and can also be written out to the /etc/modules.conf configuration file.
Users have the ability to check for new releases of a module if the module author is keeping an XSA file up-to-date on the Net. The gmodconfigedit tool helps module authors create and update those XSA files.
Finally, gmodconfig supports downloading and installing DKMS packages (work in progress).
