What does the ; operator do in the context of running commands in sequence?

The ; operator in the context of running commands in sequence allows you to execute multiple commands one after the other, regardless of whether the previous command succeeded or failed. Each command is separated by a ;, and they will be executed in the order they are written.

For example:

command1; command2; command3

In this case, command1 will run first, followed by command2, and then command3. If command1 fails, command2 and command3 will still execute.
