Today, what the editor shares with you is a detailed introduction of the shell command in linux. I believe most people don't know much about it. In order to make you understand better, the editor summed up the following content for you. Without saying much, let's move on.

In this article, we will introduce some of the basic commands used in Linux shell.

View and jump command

(1) pwd

When opening the terminal, if you need to know which directory you are currently in, you can use the pwd command, which returns an absolute path (the path starting from the root "/").

File and folder command

(1) mkdir and rmdir

Mkdir is used to create directories and rmdir is used to delete directories. Note that rmdir can only be used to delete an empty directory. To delete the directory that contains files, use rm.

(2) rm

Use the RM command to delete files and directories. But RM cannot simply delete directories. Use "rm-r" to delete the directory (with a parameter r), and at this point, the folder and the files in the folder are deleted.

The touch command is used to create files. It can produce any file, either an empty txt file or an empty zip file.

(2) mv

Use the mv command move file. We can also rename the file using the mv command, which is similar to cp.
