Free pipe software for linux

Pipebench shows the current throughput and amount of data going through a pipe. It can be used to show the progress of a large md5sum process: cat bigfile | pipebench | md5sum.

Pipebench measures the speed of a pipe, by sitting in the middle passing the data along to the next process. Works on at least Linux, OpenBSD, NetBSD, Solaris and x86, Alpha, HPPA, Sparc and Sparc64.

Compiling

Just type make to compile.

Type make install to have pipebench be installed in /usr/local/bin

KABC Client is a command line tool that provides access to the KDE address book, which is also used by applications like KAddressBook.
It can take its input from either the command line or through standard input, allowing its use in Unix shell pipe and filter constructs. Input and output text is interpreted and formatted by filters.
kabcclient can perform the following operations:
- List: --list or -L
Write all contacts of the addressbook to stdout
- Search: --search or -S
Search for contacts matching the programs input
- Add: --add or -A
Add new contacts to the addressbook
- Remove: --remove or -R
Remove contacts matching the programs input from the addressbook
- Merge: --merge or -M
Add data from the programs input to matching contacts in the addressbook
Enhancements:
- Adding installation instructions and build files for creating Debian packages.
- No changes to the program itself!

Cammgr manages a collection of web cameras. It will bring cameras online or offline, and initiate or suspend image capture operations.
Any camera can be controlled provided a driver is available. Cammgr supports multiple images per camera, default images for inactive cameras, per- user/host/camera notifications, and an easy-to- use configuration file.
Cammgr can scan Apache log files to auto-initiate image capture, and tune capture frequency can to the minimum needed to ensure that clients receive a new image on request.
Enhancements:
- Support for Axis network cameras was added.
- A bug where the pipe file descriptor was left open across shell exec was fixed.
- A client capture manager from where all capture processes are dispatched and monitored was created.
- A bug where the capture process did not go away when cammgr exited was fixed.
- Other miscellaneous cleanups were done.

Zip is a compression and file packaging utility for Unix, VMS, DOS, OS/2, Windows 9x/NT, Amiga, Atari, Macintosh, BeOS, SMS/QDOS, MVS, VM/CMS, and others.
Zip is analogous to a combination of the Unix commands tar(1) and compress(1) and is compatible with PKWAREs PKZIP and Nico Maks WinZip. Its part of the Info-ZIP project.
Main features:
- creating zipfiles in a pipe or on a device
- VMS and OS/2 extended file attributes
- conversion between Unix, MS-DOS and Macintosh text file formats
- the ability to run on most of your favorite operating systems.
Enhancements:
- fixed -R operation to match the supplied file patterns in all recursed subdirectories, like PKZIP 2.04 "-p -r" (or PKZIPC 4+ "-recurse")
- handle cases where -x, -R, and -i patterns are mixed
- new example C-Sharp code for using DLLs
- added some directory-search speedups
- fixed bug when encrypting large uncompressible files
- fixed Windows NTFS time problem
- fixed VMS logical name parse problem
- added VMS DEBUG option
- updated VMS help
- fixed selection of files to delete by date
- added -MM option where each input file pattern must match at least one file and all input files must be readable
- added check for when Zip tries to exceed seek limit in output file
- minor changes to compile with Visual C++ 2005
- added support for Unix FIFOs (named pipes)
- other minor fixes

TCPDuP is a command-line networking utility that can proxy TCP service to a remote host:port pair, thus duplicating the availability of that service.
TCPDuP project differs from using netcat and a named pipe in that it supports multiple concurrent connections. It is also faster than using a pipe and netcat due to less overhead and use of asynchronous I/O.
Other features include local command execution, a daemon mode, and verbose output/logging.
Enhancements:
- A modular framework by which new functionality can be easily developed is now used.
- Two modules are built in: pair and cmd, which duplicate a remote service and capture the I/O of a locally executed command respectively.
- It is now possible to limit bandwidth to a specified amount in bits per second, regardless of the module used.

XMMS InfoPipe is a plugin that reports XMMS status via named pipe. XMMS InfoPipe is handy if you want to add interesting real-time information for a personal web page, or a web cam page.

While theres a possibility of setting up programs to be executed by XMMS when changing songs, XMMS InfoPipe provides better introspection: You can get information on song position, song length, playlist position, status (stopped/playing/paused), song title as displayed by XMMS, and file name. The information is reported in easily parseable textual format.

The possibilities for information use are limitless. So far, here are some of the things people have been using InfoPipe for:

Showing information of XMMS on home page, webcam page, or something related (script included)
Showing player information on IRC (spotted one script for Irssi)
Using any speech synthetizer to say the song information, reducing the need for external displays, and helping listening to unfamiliar music in bed when all you have is a remote control =) (script included).

Yeah, LIRC plugin seems to support this already, but it only supports ViaVoice - this allows you to use any speech synth... or any other types of output. Just an example of flexibility - I created the script to do that at 4 oclock in the morning, and even got 99% of Perl recommendations of good coding right, even when I wasnt fully awake.

yublib is a simple Python library that allows developers to integrate yubnub into their applications.

yubutils project is a grouped project that houses three main downloads.

1. yubController - a GUI front end for yubnub that works on Windows, Linux and OS X. It may also work on other POSIX systems such as FreeBSD, OpenBSD, NetBSD, Solaris, etc..
2. yncs - a text interface for yubnub and pipe developers (included in the yublib downloads). It works with the same platforms as yubConroller.
3. yublib - the core of yubutils front ends. Python library to interface with yubnub. It is ment for developers who wish to interface with yubnub in their own applications.
