This may sound like a contradiction in terms, but I've recently needed to use single user mode (aka maintenance mode) for some time (days!) while trying rebuild a broken RAID array.
While doing this, I've found myself wanting to use a second shell for such things as checking/editing the settings in various config files or looking at system logs while the main (and only) console is tied up executing some recovery process.
What would be the recommended command to launch a second shell on another tty?
Obviously, one method might be to use
screen in tty1, but this doesn't have quite the ease of just switching sessions with Alt-F1, Alt-F2, etc.
