如何在Ubuntu中获取服务状态？

Question

我正在使用Ubuntu和upstart＆amp; System-V服务。 我需要收集一个脚本：服务状态（启动/停止）和下次启动状态（将/不会在启动时启动）

chkconfig不适合我的情况：

# chkconfig --list|grep lxc
#
# initctl list|grep lxc
shoc-lxc-net stop/waiting

我编写了脚本，它正在像json一样搜索服务状态和输出。但是我找不到如何检查服务是否会启动：对于upstart + system V。

#!/bin/bash
###############
# gether status of services:
#   output json/plain text
#   init.d & upstart

SERVICE=
SERVICEDIR="/etc/init.d"
SUDO=""
JSON_OUTPUT="true"
ONLYONESERVICE="false"
usage(){
        cat << EOL
        USAGE:
           $0 -j yes to enable json output [ by default ]
          -s yes  enable sudo [ not used by default ]
          -n servicename (if you want view status of service)

EOL
exit 1
}
