In this article let’s go through the open-source utilities that can provide us the tips and answers when we need help.

Let’s start with the default — The Linux man-pages project.

This project documents the Linux kernel and C library interfaces that are employed by user-space programs. It is definitely the most comprehensive documentation for the built-in commands. However, navigating the man pages and pinpointing the specific information that we want is definitely a bit challenging.
