Learning GNU Text Utilities

“A few weeks ago we looked at some of the GNU utilities that you
can use to work with files, check MD5/SHA1 sums and check your disk
usage. This time around I want to cover some of the utilities that
you’ll use for working with text files.

“Why text files, specifically? Well, if you’re doing much work
at the shell on Linux, you’ll start encountering a lot of text or
files that can behave like text. Log files, configuration files and
output from many commands can all be manipulated with the GNU
textutils.

“At one time, the GNU textutils were broken out into their own
package, but a few years ago they were merged into the GNU
coreutils. But for convenience sake, I’m going to keep the old
moniker because that’s a handy way of thinking about those
tools.”
