Linux ls command

The LS command is the most commonly used command under Linux. The LS command is the abbreviation of list, the lack of saving LS is used to print out the current directory of the list, if LS specifies a different directory then will be displayed in the specified directory of files and folders list. The LS command not only allows you to view the files contained in a Linux folder, but also to view file permissions (including directories, folders, file permissions), view directory information, and more. The LS command is used in a lot of everyday Linux operations!

(5)-C with the "-lt" option, the output directory content is sorted according to the file status time, sorted by the CTime field in the index node of the file. When in conjunction with the "-l" option, the ordered sentence is the state change time of the file
