Fortinet MR1 User Manual page 48

Empty strings ("") are not valid user defined strings. Command completion finishes spelling
the command when enough letters of a command are typed to uniquely identify the
command word. The command may be executed by typing <enter> (command abbreviation)
or the command word may be completed by typing the <tab> or <space bar> (command
completion).
The value 'Err' designates that the requested value was not internally accessible. This should
never happen and indicates that there is a case in the software that is not handled correctly.
The value of '-----' designates that the value is unknown.
Annotations
The CLI allows the user to type single-line annotations at the command prompt for use when
writing test or configuration scripts and for better readability. The exclamation point ('!')
character flags the beginning of a comment. The comment flag character can begin a word
anywhere on the command line and all input following this character is ignored. Any
command line that begins with the character '!' is recognized as a comment line and ignored
by the parser.
Some examples are provided below:
! Script file for displaying the ip interface
! Display information about interfaces
show ip interface 1/0/1 !Displays the information about the first interface
! Display information about the next interface
show ip interface 1/0/2
! End of the script file
