Reinventing Wheels for Fun and Profit
=====================================

   This minor node presents a number of POSIX utilities that are
implemented in `awk'.  Reinventing these programs in `awk' is often
enjoyable, because the algorithms can be very clearly expressed, and
the code is usually very concise and simple.  This is true because
`awk' does so much for you.

   It should be noted that these programs are not necessarily intended
to replace the installed versions on your system.  Instead, their
purpose is to illustrate `awk' language programming for "real world"
tasks.

   The programs are presented in alphabetical order.

Cut Program

The `cut' utility.

Egrep Program

The `egrep' utility.

Id Program

The `id' utility.

Split Program
