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