Shell implements system time and BIOS time synchronization calibration script sharing _linux Shell

The script is mainly from the defined NTP server list to get the server address to synchronize, if the first unsuccessful, will continue to change the address to sync! Not perfect place also please point out!

Copy Code code as follows:

#!/bin/bash
# NTP Network time correction script
# Run

#NTP服务器数组列表
Ntpserver= (

[0]=ntp.fudan.edu.cn
[1]=asia.pool.ntp.org
[2]=210.72.145.44
[3]=133.100.11.8
[4]=ntp.sjtu.edu.cn
[5]=time.scau.edu.cn

)

#校验 #
Servernum= ' echo ${#ntpServer [*]} '
Num=0
for ((i=0; i<= $serverNum; i++)); Todo

Echo-n "is in the process of verifying with NTP server ${ntpserver[$NUM]} ..."
/usr/sbin/ntpdate ${ntpserver[$NUM]} >>/dev/null 2>&1
If [$?-eq 0]; Then
Echo-e "\e[1;32m\t\t\t\t\t[Successful]\e[0m"
Break
Else
ECHO-E "\e[1;31m\t\t\t\t\t[failure]\e[0m"
Let num++

Sleep 2
