How to run Windows command in chain
You can chain commands in dos using the && for example
echo hello&&echo world
As per Microsoft Support:
This behavior occurs because the && command separator performs error checking. If the command to the left of the && command does not return the expected results, the commands to the right of the && command do not run.
And
When you use a single & command, error checking is not performed and all commands run.
