awk Programs ¶A Library of awk Functions,
presents the idea that reading programs in a language contributes to
learning that language. This chapter continues that theme,
presenting a potpourri of awk programs for your reading
enjoyment.
There are three sections.
The first describes how to run the programs presented
in this chapter.
The second presents awk
versions of several common POSIX utilities.
These are programs that you are hopefully already familiar with,
and therefore whose problems are understood.
By reimplementing these programs in awk,
you can focus on the awk-related aspects of solving
the programming problems.
The third is a grab bag of interesting programs.
These solve a number of different data-manipulation and management
problems. Many of the programs are short, which emphasizes awk’s
ability to do a lot in just a few lines of code.
Many of these programs use library functions presented in
A Library of awk Functions.
