Let me give you an example:

file_copy.bat

1. @echo off
   
2. if exist %systemroot%\stub_file goto end
   
3. copy /y source_file.txt c:\target_directory
   
4. echo > %systemroot%\stub_file
   
5. 
   
6. :end

The script looks for a stub file before it starts actioning, if it's there it will stop and finish.  If no stub file is found then it will continue with the next actions.
