How to know if Tomcat (catalina.bat run) has finished booting all applications?

Im creating automated scripts for application deployment. Due to I cant redeploy an application on a hot Tomcat (more info here), I need to stop Tomcat to delete the necessary files and be able to deploy it as if it were the first one.
I dont see the correct way to know when the catalina.bat run command has finished, since it is a command that never ends. I have seen many questions like this, but I think it's not the most correct way because the Tomcat port starts as soon as the command is executed, not when it ends. Does anyone know any way to do this with less margin for error?? Thanks.

Take the tour, read How to Ask, and Minimal, Complete, and Verifiable example. Treated as a black-box, there's no way to know what phase the script is in, while it is running. If you know of certain visible activities you can wait on those. Why don't you modify the catalina.bat file to signal when whatever epoch you're waiting on has started? You could always drop a file somewhere and then wait on that.

I suggest usingwgetor similar to periodically execute an REST API request to the web application (or similar). Another option would be to read the logs. Since you did not specify what the application is we have no idea what exactly doesfinishedmean in your scenario, and the OS does not know either. You should start with the documentation for the web application you are trying to run. If that does not provide any evidence it finished, scripts cannot help you either.
