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

If you know the name of the process, as returned from the command tasklist, then you can run taskkill with a filter on the process name, i.e. /FI IMAGENAME eq %process_name%.

For example, to kill all of the processes named nginx.exe run:

    taskkill /F /FI "IMAGENAME eq nginx.exe"

Which "reads in English": kill all tasks (forcefully if needed via /F) that match the filter /FI "IMAGENAME equals nginx.exe".
