Self-tutoring about Windows command prompt: the tutor mentions a way to combine commands on one line.
a_command & another_command
will perform both commands if possible. Even if it can’t do the first, it will still attempt the second.
a_command && another_command
it seems, will stop if it can’t perform the first command. However, if it can perform the first it will move on to the second.
