This command list is a list of commands available on a Linux system. As you know, Linux has many distributions with different system types based on the base system used by the distribution.
Therefore, although basically all the basic commands on Linux are the same, maybe some of the commands below cannot be executed on the distribution you are using, because these commands are commands on other Linux distributions, and some commands can only be used after you install additional package.
If you’re just looking for the basic commands, you don’t have to go through all these long pages, you can find them on the Linux Basic Commands and Functions page — which you can see more easily.
