LS command details

The LS command is the most commonly used command in Linux. The LS command is short for list. By default, LS is used to print the list of the current directory. If ls specifies other directories, the list of files and folders in the specified directory is displayed. By using the LS command, you can view not only the files contained in Linux folders, but also the File Permission (including the directory, folder, and file permission) to view the directory information.
