        no output subprocess.

        #### specified pattern
        
        reload only '*.py' file modified.
        
        ```sh
        (pywatcher) denzownoMacBook-Pro:pywatcher denzow$ pywatcher -t ./ -c 'ping localhost' -p '*.py'

        #### send signal change
        
        pywatcher send **SIGTERM** to process when reload. if you set `--signal KILL` option, send **SIGKILL**.
        
        ```sh
        (pywatcher) denzownoMacBook-Pro:pywatcher denzow$ python pywatcher/command.py -t . -c 'echo reload'  -s 1 --signal KILL
