Usage guidelines
Some commands might take a long time to complete in some situations, for example, when the
ping
command has 1000 packets to send or when the
tracert
command is used for an unreachable
destination. Before such a command is completed, you can stop the command by pressing the
shortcut key for terminating tasks.
Whether a command can be terminated by
Ctrl+C
by default depends on the software
implementation of the command. For more information, see the description of the command.
As a best practice, use a key sequence as the shortcut key. If you define a single character as the
shortcut key, pressing the key while a command is being executed stops the command. If no
command is being executed, the result depends on the following:
•
If you are managing the local device, pressing the key enters the character as a common
character.
•
If you Telnet to another device and manage the remote device, pressing the key does nothing.
You can execute this command multiple times, but only the most recent configuration takes effect. To
view the current shortcut key definition, use the
display current-configuration
command.
This command is available in both user line view and user line class view:
•
If the setting in user line view is not the default setting, the setting in user line view takes effect.
•
If the setting in user line view is the default setting but the setting in user line class view is not,
the setting in user line class view takes effect.
Examples

a
as the shortcut key for terminating a task.
<Sysname> system-view
[Sysname] line aux 0
[Sysname-line-aux0] escape-key a
