GNU Utilities

We’ll go over a short introduction to GNU utilities and output redirection.

GNU utilities were completed in 1987. The idea behind them is to provide open-source software for Unix developers. Most of the original Unix programs were proprietary. This means that we would need to buy a Unix system and launch them there.

GNU utilities copy all features of their originals. Therefore, they follow the Unix philosophy, too. By using them, we get all the benefits of the universal text format.
