| When
you use a terminal window, a shell prompt appears on the screen. At
the shell prompt, you can type commands. Commands are requests from
the user telling the system to perform an action.
The
general format for Linux commands is:
command
[option(s)] [argument(s)]
Between
the command and options is a space. Another space is placed between
the options and arguments. These spaces are called delimiters because
they delimit (or separate) one section of the command from another.
The
following are examples of commands that do not require all three
parts.
Note:
Each sentence is a separate command.
| $ ls -la

| $ |
| $ head
-5 /etc/passwd |
| $ |
| $ cat
/etc/passwd |
| $ |
| $ date |
