How do I run a batch script from within a batch script?

Question

How do I call another batch script from within a batch script?

I want it to execute in an if statement.

Answer 1

If you wish to open the batch file in another window, use start. This way, you can basically run two scripts at the same time. In other words, you don't have to wait for the script you just called to finish. All examples below work:

start batch.bat
start call batch.bat
start cmd /c batch.bat

If you want to wait for the script to finish, try start /w call batch.bat, but the batch.bat has to end with exit.
