Free stdin is not a tty software for linux

LINGOT is a musical instrument tuner. LINGOT is easy to use, accurate, and highly configurable. Originally conceived to tune electric guitars, its configurability gives it a more general character. (Tuning another instruments has not been tested).
It looks like an analogic tuner, with a gauge indicating the relative shift to a certain note --found automatically as the closest note to the estimated frequency--, indicating that note and its frequency.
The note will be found automatically, since the program hasnt any manual function mode (indicating the note to tune manually), for mantaining its general purpose.
We recommend using the tuner in conjunction with a sound mixer for selecting the desired recording source and the signal recording levels.
Main features:
- Accurate.
- Easy to use. Just plug in your instrument and run tuner.
- Very configurable via GUI. Its possible to change any parameter while the program is running, without editing any file.
- It works in an automatic way. It isnt necessary specify the note to tune; the program guesses it.
- Its free software. It has GPL license.
- Tuning other instruments than guitars is possible. Since this program guesses the note you are playing, it can be used to tune a piano, a bass, a violin, etc.
Enhancements:
- Files have been reorganized to a more "GNU-like" structure.
- Multi-lingual support has been added.

IO::Tty is a Perl module to low-level allocate a pseudo-Tty, import constants.

SYNOPSIS

use IO::Tty qw(TIOCNOTTY);
...
# use only to import constants, see IO::Pty to create ptys.

IO::Tty is used internally by IO::Pty to create a pseudo-tty. You wouldnt want to use it directly except to import constants, use IO::Pty. For a list of importable constants, see IO::Tty::Constant.

Windows is now supported, but ONLY under the Cygwin environment, see http://sources.redhat.com/cygwin/.

Please note that pty creation is very system-dependend. From my experience, any modern POSIX system should be fine. Find below a list of systems that IO::Tty should work on. A more detailed table (which is slowly getting out-of-date) is available from the project pages document manager at SourceForge http://sourceforge.net/projects/expectperl/.

If you have problems on your system and your system is listed in the "verified" list, you probably have some non-standard setup, e.g. you compiled your Linux-kernel yourself and disabled ptys (bummer!). Please ask your friendly sysadmin for help.

If your system is not listed, unpack the latest version of IO::Tty, do a perl Makefile.PL; make; make test; uname -a and send me (RGiersig@cpan.org) the results and Ill see what I can deduce from that. There are chances that it will work right out-of-the-box...

If its working on your system, please send me a short note with details (version number, distribution, etc. uname -a and perl -V is a good start; also, the output from "perl Makefile.PL" contains a lot of interesting info, so please include that as well) so I can get an overview. Thanks!

ipsort script sorts a STDIN of IP addresses to STDOUT. It sorts by the first octet, then by the second, the third and the fourth.

Usage: Takes Standard in or a file or list of files. So ipsort < file1 > < file2 > or cat < file > | ipsort
Its quite clever and looks for an IP address on each line, rejecting if it doesnt find one

Options:

-c or --commas Separate the list by space-separated commas, rather than one IP per line.
-u or --unique Uniquely sort the list as well, to avoid duplicate IPs.
-s or --string Use this string to separate the IPs. Eg. -s :
-m or --multiple Search for multiple IP addresses per line.
-h or --help Display this usage message.

SdlZombies project is a zombie game clone.
The purpose of the game is to attract zombies and make them fall in holes.
Enhancements:
- Remove : all tty debug output.
- Final version !

Nixs Web-based SSH client has a backend written in C/glib and a frontend written in PHP. The project talks to the backend via a Unix socket.
The backend maintains a number of SSH processes in TTYs, reads their TTYs, and sends the contents to PHP for formatting. PHP accepts input and passes it to the correct TTY for processing.
Enhancements:
- CR/LF interpretation was improved.
- Escape sequences were added.
- GOption command line parsing was added.

libproclist is a very simple and easy to use C library that returns the process listing using ps.

It is very portable and is known to work on Linux, Irix, AIX, Solaris and OpenBSD. libproclist doesnt, however, work for FreeBSD.

Usage:

The installation is as simple as `configure, `make and `make install.

The interface of the library is:

struct pl_procinfo
{
pid_t pid;
pid_t ppid;
uid_t euid;
gid_t egid;
char *tty;
char *cmd;
};

struct pl_procinfo **pl_proclist;
int pl_proclist_count;

/*
Get the process list.
Return:
-1: Internal error
0: Error executing ps
>0: Number of processes
*/
int pl_get_proclist();

Just call pl_get_proclist() and it will allocate the pl_proclist table which will contain pl_proclist_count elements. Each element is a process.

Snoop is a A GNU/Linux file descriptor monitoring tool inspired by FreeBSDs watch. Snoop project goes beyond simple TTY snooping by allowing the interception of any file descriptor.
You can attach on the fly to regular files, TTYs, named pipes, character devices, and pretty much anything that is represented by a file descriptor and addressable in the standard name space. It currently supports only recent 2.6 Linux kernels.
Enhancements:
- This release addresses the compatibility issues with recent kernels.
- It also extends the monitoring capabilities to parent directories in order to intercept creation events and attach targets on the fly.
