CENTOS7 under command note-ls

The LS command is probably one of the most commonly used commands under Linux, and LS is the abbreviation for list. Because there is too much information on a Linux directory or file record, the default LS displays only non-hidden directories and filenames. LS Displays the file name in this directory directly when no parameters are added.

The LS command format is:

ls [-aadffhilnrrst] directory name
