ls [OPTIONS] [FILES]

ls displays a list of the names of all files in the current working directory when used without any options or arguments:

ls

The files are listed alphabetically in as many columns as your terminal will allow:

cache  db  empty  games  lib  local  lock  log  mail  opt  run  spool  tmp

To list files in a single directory, use the ls command with the directory path as an input. To list the contents of the /etc directory, for example, type:

ls /etc

You can also use space to separate several directories and files:

ls /etc /var /etc/passwd

You'll get a notice claiming that ls can't open the directory because the user you're logged in with doesn't have read permissions:

ls /root

Output

ls: cannot open directory '/root': Permission denied

There are several options for the ls command. We'll go over the most popular solutions in the sections below.
