With your tip, this script : import os p = os.popen4(r'cmd /k') p[0].write('dir *.bat /B\r\n') p[0].flush() p[0].write('dir *.cfg \r\n') p[0].flush() p[0].write('exit\r\n') p[0].flush() print ''.join(p[1].readlines()) run perfectly @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
