The method tcsetpgrp() sets the process group associated with the terminal given by fd (an open file descriptor as returned by os.open()) to pg.
fd -- This is the file descriptor.
pg -- This set the process group to pg.
# !/usr/bin/python import os, sys # Showing current directory print "Current working dir :%s" %os.getcwd() # Changing dir to /dev/tty fd = os.open("/dev/tty",os.O_RDONLY) f = os.tcgetpgrp(fd) # Showing the process group print "the process group associated is: " print f # Setting the process group os.tcsetpgrp(fd,2672) print "done" os.close(fd) print "Closed the file successfully!!"
When we run above program, it produces following result:
Current working dir is :/tmp the process group associated is: 2672 done Closed the file successfully!!
