GDB, the GNU Project debugger, allows you to see what is going on `inside' another program while it executes -- or what another program was doing at the moment it crashed. GDB can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act: Start your program, specifying anything that might affect its behavior. Make your program stop on specified conditions. GDB version 7.7 Version 7.7 of GDB, the GNU Debugger, is now available for download. An errata list (PROBLEMS) and documentation are also available.
FSF's Position regarding SCO's attacks on Free Software News February 6th, 2014: GDB 7.7 Released! The latest version of GDB, version 7.7, is available for download. Changes in this release include: Enhanced Python scripting support. January 8th, 2014: GDB 7.7 branch created. Gawk. Gawk If you are like many computer users, you would frequently like to make changes in various text files wherever certain patterns appear, or extract data from parts of certain lines while discarding the rest.
To write a program to do this in a language such as C or Pascal is a time-consuming inconvenience that may take many lines of code. The job is easy with awk, especially the GNU implementation: gawk. The awk utility interprets a special-purpose programming language that makes it possible to handle simple data-reformatting jobs with just a few lines of code.
The source code for the latest release of GNU awk is available from the GNU project's ftp server and its many mirrors. The main gawk manual is available online. A separate gawkinet manual for the special TCP/IP networking features of GNU awk is also available. Bug reports and feature suggestions for gawk should be sent to bug-gawk@gnu.org.

Instead, it is used to filter text, i.e., it takes text input, performs some operation (or set of operations) on it, and outputs the modified text. sed is typically used for extracting part of a file using pattern matching or substituting multiple occurrences of a string within a file.
