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.
