GNU awk

The GNU awk (gawk) is a GNU re-implementation of the AWK programming language/macro pre-processor.

Paul Rubin and Jay Fenlason (FSF) wrote gawk, to be compatible with the original version of awk distributed with the Seventh Edition of UNIX. John Woods contributed a number of bug fixes. David Trueman, with contributions from Arnold Robbins, made gawk compatible with the new version of UNIX awk (nawk).

The initial DOS port was done by Conrad Kwok and Scott E. Garfinkle. Scott Deifik maintains the port to MS-DOS using DJGPP. The port to OS/2 was done initially by Kai-Uwe Rommel, with contributions and help from Darrel Hankerson. Later Andreas Buening maintained the OS/2 port.

Charset support (for macro/text processing)
8-bit ASCII (256 Characters according to current codepage). No support for Unicode or DBCS, some older versions of the tool support DBCS and Shift JIS file names.
