linux - Python startup script using STDOUT for outputs, using init.d method -

my environment debian jesse on embedded arm display.

i using bash script automatically launch app using init.d method. launches second python script daemon handles application on startup , reboot.

because run way best of knowledge daemon background process, , disconnects stdout , stdin python script.

the system , application single purpose, spamming console outputs background process not not problem, desired. outputs can ssh or serial console display , see live debug outputs or exceptions.

i have looked possible ways force process foreground, or redirect outputs stdout have not found definite answer when script run @ startup.

my logging file working perfect , otherwise app works in state in. when need debug stop application , run manually outputs.

i have considered using sockets redirect outputs app, , running separate script listening print console... seems less ideal , better solution might exist.

is there methods achieve or should accept this.

edit 1 (additional details)

because using multiple logs multiple processes have created logger class. stream handler uses default should sys.stderr.

import logging import logging.handlers  class loggersetup(object):      def __init__(self, logname, logfilenameandpath, logsizebytes, logfilecount):          log = logging.getlogger(logname)         log.setlevel(logging.info)          formatter = logging.formatter('%(asctime)s - %(levelname)s - ' + logname + ' - %(message)s',datefmt="%m-%d %h:%m:%s")         # add log message handler logger          if(logfilecount > 0):              filehandler = logging.handlers.rotatingfilehandler(logfilenameandpath, maxbytes=logsizebytes, backupcount=logfilecount)             log.addhandler(filehandler)             filehandler.setformatter(formatter)          consolehandler = logging.streamhandler()         log.addhandler(consolehandler)         consolehandler.setformatter(formatter)          log.info(logname + ' initialized') 

for more reference here startup script launch on boot. runs python run.py handles rest of startup process.
