| Synopsis | |

| :: | |
| history | |
| Description | |
| ----------- | |
| The *history* command shows a list of previously entered commands on the | |
| command line. When U-Boot starts, this it is initially empty. Each new command | |
| entered is added to the list. | |
| Normally these commands can be accessed by pressing the `up arrow` and | |
| `down arrow` keys, which cycle through the list. The `history` command provides | |
| a simple way to view the list. | |
| Example | |
| ------- | |
| This example shows entering three commands, then `history`. Note that `history` | |
| itself is added to the list. | |
