This command shows the contents of the command history buffer.

Command Mode

Normal Exec, Privileged Exec

Command Usage

The history buffer size is fixed at 10 Execution commands and 10 Configuration commands.

Example

In this example, the show history command lists the contents of the command history buffer:

Console#show history Execution command history:

2 config

1 show history

Configuration command history: 4 interface vlan 1

3 exit

2 interface vlan 1

1end

Console#

The ! command repeats commands from the Execution command history buffer when you are in Normal Exec or Privileged Exec Mode, and commands from the Configuration command history buffer when you are in any of the configuration modes. In this example, the !2 command repeats the second command in the Execution history buffer (config).
