linux启动脚本问题

[csz429180]

目前遇到了一个linux启动脚本的问题，有多个服务用到了同一个脚本，但只有2个服务能够正确的返回status的信息，其他服务调用service xxxx status后返回的信息不正确 哪怕该服务已经停掉了 依然返回了它的pid 用./的方式执行一样的情况 但用 bash /etc/init.d/xxx 执行却是OK的 下面是脚本代码
#! /bin/bash

#
# ENMC 服务启动脚本。
#

# Source function library
if [ -f /etc/init.d/functions ] ; then
. /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ] ; then
. /etc/rc.d/init.d/functions
else
exit 1
fi
