How to Use Command Lines
This section describes how to use command lines and some techniques to improve operating efficiency.
- Entering Command Views
- Setting Command Levels
The system divides commands into four levels and sets the command level in the specified view. The device administrator can change the command level as required, so that a lower-level user can use some high-level commands. The device administrator can also change the command level to a larger value to improve device security. - Editing Command Lines
- Using Command Line Online Help
When using a command line, you can use the online help to obtain real-time help without memorizing a large number of complex commands. - Interpreting Command Line Error Messages
If a command is entered and passes syntax check, the system executes it. Otherwise, the system reports an error message. - Using the undo Command Line
- Displaying History Commands
- Using Command Line Shortcut Keys
- Executing Commands in a Batch
If multiple commands are frequently used consecutively, you can edit these commands to be executed in batches. This simplifies command input and improves efficiency.
