| 13 | Description |
| 14 | ----------- |
| 15 | |
| 16 | The *history* command shows a list of previously entered commands on the |
| 17 | command line. When U-Boot starts, this it is initially empty. Each new command |
| 18 | entered is added to the list. |
| 19 | |
| 20 | Normally these commands can be accessed by pressing the `up arrow` and |
| 21 | `down arrow` keys, which cycle through the list. The `history` command provides |
| 22 | a simple way to view the list. |
| 23 | |
| 24 | Example |
| 25 | ------- |
| 26 | |
| 27 | This example shows entering three commands, then `history`. Note that `history` |
| 28 | itself is added to the list. |
