The Shell and Its Commands
We’ll be doing a lot of things in the shell, such as installing packages, making new users, creating directories, modifying permissions of files, and so on. These will be the basics but will be your first interaction with the shell to understand what is happening behind it and to get more confident. In order to improve our effectiveness with the shell, we’ll be devoting an entire chapter to it this time around.
In this chapter, we will cover the following topics:
- A basic definition of a shell in order to understand how it works, including an overview of its features and a description of the most common shells
- How to use basic commands in order to get familiarized with Linux (in this chapter, CentOS version 8 will be used)
- Basic notions about how to use commands to change the ownership of files and directories
