Free stdin software for linux

PipeBandwidth is a program that measures the speed at which data goes through a pipe and prints statistics to stderr.

Basically, it just reads from stdin, writes data back to stdout, and measures the speed. PipeBandwidth can be useful to measure transfer rates while sending data through netcat or compressing with gzip or bzip2.

Amigadepacker uncompresses various compression formats used on AmigaOS.
The supported formats are PowerPacker, XPK SQSH, and MMCMP. Amigadepacker can also decrypt PowerPacker encrypted data files.
Usage: amigadepacker [-c] [-h] [-p] [-v] FILE ...
-c Unpack to stdout.
-h Print this.
-p Do not depack anything, just pretend to. Useful for searching packed
files. Names of packed files will be printed to stderr. Pretend mode
always returns success if arguments are valid.
-v Print version information.
Example 1: Depack file:
amigadepacker foo
Example 2: Depack file from stdin to stdout:
amigadepacker -c < foo > outfile
Enhancements:
- StoneCracker 4.04 format support was added, and decompressing a file through stdin was fixed.

GINS a.k.a. Gtk INterface for Script is a way to add GTK interfaces to scrpit languages that doesnt have any GTK bindigs, like BASH scripts. GINS load a GLADE xml file, using libglade. Then run the script, linking to his stdin & stdout.
Now script can communicate to GINS simply writting to stdin and reading from stdinput.
GINS pass to script every events that occours to gtk widgets, and script can react.
Enhancements:
- BradC: This version of GINS adds the ability to get boolean and double and the ability to set ints. So we can both get and set; int, str, double and boolean.

Daniels Colorize.pl is a short script that reads from stdin and writes to stdout. Rows that match a users search strings will be colorized with user-defined colors. Command line options are available. Colorization is done via ANSI escape codes.
Use any kind of stdin text stream and it will send it on stdout colorized.
e.g.: ls -lF | colorize.pl [options]
colorize.pl will print out every line from stdin to stdout. However rows with matching strings, will be colorized with your choice of color.
Options:
Options format: -[style][foreground][background]:[searchstring]
[style]
n = normal, l = light, u=underscore, i = inverted, b = blinking
[foreground color]
0= black, 1= red, 2= green, 3= yellow, 4= blue, 5= purple, 6= cyan, 7= white
[background color]
0= black, 1= red, 2= green, 3= yellow, 4= blue, 5= purple, 6= cyan, 7= white
[searchstring]
string
Example:
cat debug.txt | colorize.pl -u17:error -n37:warning -b10:funny
will colorize lines with the word:
- "error" underscored in red front color and white background
- "warning" in green front color and white background
- "funny" blinking in red front color with black background
Enhancements:
- Allows no background colors.
- Support for choosing between colorizing whole rows or just the matching words.

sudoku solver by darsie project is a console-based sudoku solver.

sudoku solver by darsie is a console program that reads data from stdin (typically redirected from a file) and prints a possibly partial result. Definitive numbers are printed all over their fields.

Other fields contain the numbers that are not yet excluded.

Three solving rules are implemented and most sudokus are solved in a few milliseconds.

Usage:
