我不知道你用的什么系统，但在Linux，如果你想查询名称服务正在运行将使用commnand

chkconfig --list 

acpid      0:off 1:off 2:off 3:off 4:off 5:off 6:off 
alsa-restore    0:off 1:off 2:off 3:off 4:off 5:off 6:off 
alsa-store    0:off 1:off 2:off 3:off 4:off 5:off 6:off 
anacron     0:off 1:off 2:off 3:off 4:off 5:off 6:off 
apache2     0:off 1:off 2:on 3:on 4:on 5:on 6:off 
apparmor     0:off 1:off 2:off 3:off 4:off 5:off 6:off S:on

bootlogd     0:off 1:off 2:off 3:off 4:off 5:off 6:off 
brltty     0:off 1:off 2:off 3:off 4:off 5:off 6:off S:on

dmesg      0:off 1:off 2:off 3:off 4:off 5:off 6:off 

我认为Python或bashell能做到这一点。
