Using the do command as a shortcut

You can use the do command to save time when you are working in any configuration mode and you want to run a command in privileged EXEC mode.

For example, if you are configuring an Ethernet interface and you want to execute a privileged EXEC mode command, such as the dir command, you would first have to exit the Interface configuration mode. By using the do command with the dir command, you can ignore the need to change configuration modes, as shown in the following example.

device(config-if-eth-1/2)# do dir
