coreutils are your friends

Once upon a time there was textutils, a small set of classic Unix utility programs to play with text files.

If in a file you had to print out, or reverse, or select lines, or edit the text stream, paginate it, wrap it, select the beginning or the ending lines and so on, you can use that small commands of the Unix tradition, lasting good old days of Real Programmers.

Nowdays textutils are incorporated in a huge set called coreutils with a lot of other stuff.

They are powerful tools to know even to make your data homeworks, so please make yourself acquainted with them. You’ll be grateful forever.

We’ve already seen a simple example, and many other will come. But remind that coreutils are your friends.
