This section 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”
The programs are presented in alphabetical order.
