This article mainly introduces "how to write Shell script to realize synchronous calibration of system time and BIOS time". In daily operation, it is believed that many people have doubts about how to write Shell script to realize synchronous calibration of system time and BIOS time. The editor consulted all kinds of materials and sorted out simple and useful operation methods. I hope it will be helpful for you to answer the question of "how to write Shell scripts to achieve system time and BIOS time synchronization calibration"! Next, please follow the editor to study!

The code is as follows:

#! / bin/bash

# NTP Network time Correction script

# run

# NTP server array list

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

)

# check #

ServerNum= `echo ${# ntpServer [*]} `

NUM=0

For ((iTuno; I > / dev/null 2 > & 1)

If [$?-eq 0]; then

Echo-e "\ e [1bot 32m\ t\ t [success]\ e [0m"

Break

Else

Echo-e "\ e [1x 31m\ t\ t [failure]\ e [0m"

Let NUM++

Fi

Sleep 2

Done

# set BIOS time to be consistent with system time
