when_changed ============ Runs a Command when a file changes (Windows only) usage: when_changed (file path) (command) (optional-parameters) when_changed C:\somedir\foo.txt myapp.exe when_changed C:\somedir\*.txt myapp.exe when_changed C:\somedir\**.txt myapp.exe (recursive) when_changed C:\somedir\* myapp.exe when_changed C:\somedir\** myapp.exe (recursive) when_changed fileincurrentdir.txt myapp.exe when_changed C:\somedir\foo.txt myapp.exe bar wibble 123 when_changed C:\somedir\*.txt myapp.exe %file% Notes: - Press 'F' to force the command to run. - The utility will wait for the command to exit before running it again. - The utility will will re-run the command if file changes whilst command is running. - Beware of creating an infinite loop! - (file path) must be a file path with wildcards -- not a directory. - The search is recursive if the filename contains a double-asterisk ** (wildcards in directory names not supported.) - Include a %file% parameter to pass the full path of the changed file to the target application. **Note this parameter omitted when 'force running' the target application**.
