shuffling

In the world of Linux, efficiency is key. Whether you're a system administrator, a developer, or a data scientist, manipulating text data quickly and effectively can be crucial. One handy tool that deserves more attention is shuf, a command-line utility that randomly shuffles the lines of a file or input stream. This is particularly useful for tasks such as generating random samples, creating randomised lists, or even setting up conditions for simulations. shuf is a utility in GNU Coreutils, available by default on most Linux distributions. It reads a sequence of lines from a file (or standard input), randomly permutes them, and outputs the result.
