> 1. Type "echo a", press <Enter>
> 2. Type "echo b", press <Enter>
> 3. Now you are to select previously executed commands (echo b, echo a) using "up" cursor key.
> 4. Now only press <Enter> without entering any shell command.
> 5. Try to select previously executed commands using "up" cursor key. "echo b" is gone, however "echo a" will still be recalled.
