Reading a value from a file in a windows batch script

Question

I\'m trying to read a value from a file and use it in a subsequent command.

I have a file called AppServer.pid which contains the process id of my app serve

Answer 1

This works:

SET /P VALUE_FROM_FILE= < AppServer.pid
taskkill /pid %VALUE_FROM_FILE% /f

The /P parameter used with SET allows you to set the value of a parameter using input from the user (or in this case, input from a file)
