优化chkconfig

只保留系统服务： crond /network /sshd /rsyslog /sysstat 其他服务全部关闭

首先将所有 3:on的服务名过滤出来，然后 grep -vE 排除需要的服务

#!/bin/bash

. /etc/init.d/functions
service=`chkconfig --list | grep :on | awk '{print $1}'| grep -vE "crond|sshd|network|rsyslog|sysstat"`

for serve in $service;do
        chkconfig $serve off
        action "$serve off" /bin/true
done

执行结果：

[root@rhel6 script]# bash chkconfig.py

ubuntu中 chkconfig对应的命令是：sysv-rc-conf
