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

This minor node presents a number of POSIX utilities 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.  Nor may all of these
programs be fully compliant with the most recent POSIX standard.  This
is not a problem; their purpose is to illustrate 'awk' language
programming for "real-world" tasks.

   The programs are presented in alphabetical order.

* Menu:

* Cut Program::                 The 'cut' utility.
* Egrep Program::               The 'egrep' utility.
* Id Program::                  The 'id' utility.
* Split Program::               The 'split' utility.
* Tee Program::                 The 'tee' utility.
* Uniq Program::                The 'uniq' utility.
* Wc Program::                  The 'wc' utility.
