Parameters

alias: Specifies an alias, a case-sensitive string of 1 to 20 characters. An alias cannot be alias or contain spaces or quotation marks (").

command: Specifies a command string. Make sure the command string meets the syntax requirements.

Usage guidelines

System-defined command aliases cannot be deleted.

You can configure one or more aliases for a command or the starting keywords of commands. Then, you can use the aliases to execute the command or commands. If the command or commands have undo forms, you can also use the aliases to execute the undo command or commands.

For example, if you configure the alias shiprt for display ip routing-table, you can enter shiprt to execute the display ip routing-table command. If you configure the alias ship for display ip, you can use ship to execute all commands that start with display ip:

· Enter ship routing-table to execute the display ip routing-table command.

· Enter ship interface to execute the display ip interface command.

The command string can include up to nine parameters. Each parameter starts with the dollar sign ($) and a sequence number in the range of 1 to 9. For example, you can configure the alias shinc for the display ip $1 | include $2 command. Then, to execute the display ip routing-table | include Static command, you need to enter only shinc routing-table Static.

To use an alias for a command that has parameters, you must specify a value for each parameter. If you fail to do so, the system informs you that the command is incomplete and displays the command string represented by the alias.

Examples

# Configure shiprt as the alias for the display ip routing-table command and verify the configuration.

<Sysname> system-view

[Sysname] alias shiprt display ip routing-table

[Sysname] shiprt

To display the current escape key, use the display current-configuration | include escape-key command.

delay seconds: Specifies the time (in seconds) for the system to wait before executing the commands again. The value range is 0 to 4294967295. The default is 1.

Usage guidelines

To repeat a command, first enter the view for the command. To repeat multiple commands, first enter the view for the first command.

The repeat command executes commands in the order they were executed.

The system waits for your interaction when it repeats an interactive command.

The system skips all password configuration commands.

The number of commands to be repeated in the command history buffer is determined by the minimum value of the following:

· Number of the most recently executed commands in the command history buffer specified by the repeat command.

· Size of the command history buffer specified by the history-command max-size command.

· Number of the commands in the command history buffer.

Examples

# Configure the system to execute the two most recently executed commands (display cpu-usage and display clock) three times at an interval of 10 seconds.
