“This article gives some insight in to the tricks that you can
do with AWK. It is not a tutorial but it provides real live
examples to use.”
“…Although regular expressions are only slightly touched
in this article, you need to know them to get the maximum from awk
and other commands like sed and grep.“
“The key question is whether this awk command is really useful.
The answer is definitly yes! It could be useful for a normal user
to process text files, re-format them etc… For a system
administrator AWK is really a very important utility. Just walk
around /var/yp/Makefile or look at the initialization scripts . AWK
is used everywhere.”
