批量删除nagios的停机计划

当我们误操作，批量设置了主机和服务的计划维护时间，如何批量删除呢？下面通过一个脚本轻松搞定～～～
#!/bin/bash
#eg:
# ./Del_downtime.sh 877 885 hosts     
# 删除System--Downtime下的维护计划中Scheduled Host Downtime从877到885项设置
# ./Del_downtime.sh 886 894 services 
# 删除System--Downtime下的维护计划中Scheduled Service Downtime从886到894项设置
if [ $3 == "hosts" ];then
 for((i=$1;i<=$2;i++));do echo "\[`date +%s`\] DEL_HOST_DOWNTIME;$i"  >> /usr/local/nagios/var/rw/nagios.cmd;done
elif [ $3 == services ];then
 for((i=$1;i<=$2;i++));do echo "\[`date +%s`\] DEL_SVC_DOWNTIME;$i"  >> /usr/local/nagios/var/rw/nagios.cmd;done
else
 echo "Input error...."
