Description
The ls command displays the listing of a specified directory. If you omit the directory name, ls displays the contents of the current directory. By default, ls does not list files whose names begin with a period (. ); to see all files, type ls -a. You can see full details of files (including size, user and group ownership, and read-write-execute permissions) with the ls -l command.
