1.2 Command Line Interface
28
UM Config GRS
Release 8.0 09/2019
When you enter a command and press the <Enter> key, the Command Line Interface starts the
syntax analysis. The Command Line Interface searches the command tree for the desired
command.
When the command is outside the Command Line Interface command range, a message informs
you of the detected error.
Example:
The user wants to execute the
show system info
command, but enters
info
without
f
and presses
the <Enter> key.
The Command Line Interface then displays a message:
(GRS)>show system ino
Error: Invalid command 'ino'
Command tree
The commands in the Command Line Interface are organized in a tree structure. The commands,
and where applicable the related parameters, branch down until the command is completely
defined and therefore executable. The Command Line Interface checks the input. When you
entered the command and the parameters correctly and completely, you execute the command
with the <Enter> key.
After you entered the command and the required parameters, the other parameters entered are
treated as optional parameters. When one of the parameters is unknown, the Command Line
Interface displays a syntax message.
The command tree branches for the required parameters until the required parameters have
reached the last branch in the structure.
With optional parameters, the command tree branches until the required parameters and the
optional parameters have reached the last branch in the structure.
1.2.8 Structure of a command
This section describes the syntax, conventions and terminology, and uses examples to represent
them.
Format of commands
Most of the commands include parameters.
When the command parameter is missing, the Command Line Interface informs you about the
detection of an incorrect command syntax.
This manual displays the commands and parameters in the
Courier
font.
