I find this approach Linux and its commands. It focuses on the small core commands that you will use the 80% or 90% of the time, trying to simplify the usage of the more complex ones. All those commands work on Linux, and institutions, starting from the 70's The macOS terminal gives you access to the same exact commands I'll describe in the rest of this handbook. Microsoft has an official Windows Subsystem for Linux

and institutions, starting from the 70's The macOS terminal gives you access to the same exact commands I'll describe in the rest of this handbook. Microsoft has an official Windows Subsystem for Linux work with the underlying operating system. It allows you to execute operations using text and commands, and it provides users advanced features like being able to create scripts. 7 This is important: we'll see in detail the most common commands you will use. 2. man The first command I want to introduce is a command that will help you understand all the other commands. 8 Every time I don't know how
