Many computer users need to manipulate text files: extract and then
operate on data from parts of certain lines while discarding the rest,
make changes in various text files wherever certain patterns appear,
and so on. To write a program to do these things in a language such as
C or Pascal is a time-consuming inconvenience that may take many lines
of code. The job is easy with awk, especially the GNU implementation:
Gawk.
The awk utility interprets a special-purpose programming language that
makes it possible to handle many data-reformatting jobs with just a few
lines of code.
