| 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. |
