What is && in bash? In bash—and many other programming languages—&& means “AND”.
And in command execution context like this, it means items to the left as well as right of && should be run in sequence in this case.

What is & in bash? And a single & means that the preceding commands—to the immediate left of the &—should simply be run in the background.
