Usage Guidelines

Usage Scenario

The CLI can automatically save the historical commands that you enter. This function is similar to that of Doskey. You can invoke and run the historical commands at any time.

Precautions

If the historical command buffer is used up and a new command is entered, the command line interface deletes the earliest command in the buffer in the sequence the commands were entered.
The formats of the saved historical commands are the same as those of the commands entered by users. If the commands entered by a user are incomplete, the saved historical commands are also incomplete.
If a user runs the same command several times, only the earliest command is saved as a historical command. However, if the same command is entered with different formats, they are saved as different commands.

Example

# Set the size of the historical command buffer to 20.

<HUAWEI> system-view

[HUAWEI] user-interface console 0
