This cheatsheet includes a list of basic and advanced useful Linux commands that every Kali Linux user must know.
Mastering the command line is critical for every Kali user. There are many things you can do via command line that cannot be done in a standard GUI environment. Tasks that take minutes or even hours to do on a desktop environment (GUI) can be done in a matter of seconds from the command line.
To give you an example, here's a one line linux command to download an entire website:
wget -r domain.com
If you tried the same on a desktop environment, you'd have to save each page of the site, one by one.

This is only one of many examples as to how powerful the command line truly is. There are many other tasks on Linux that can only be done from the command line.
