1、说明

在linux 环境下，新增开机自启动脚本

2、环境说明

硬件环境： NVIDIA 开发板
软件环境： Ubuntu 18

3、操作

3.1 增加开机脚本

 sudo  vi /etc/init.d/test.sh

其中脚本的内容如下

#!/bin/sh
### BEGIN INIT INFO
# Provides:          test.sh
# Required-Start:    $remote_fs
# Required-Stop:
# Should-Start:      
# Default-Start:     2 3 4 5
# Default-Stop:
# X-Interactive:     true
# Short-Description: Just test script
### END INIT INFO




exit 0

3.2 将脚本添加到开机服务

cd  /etc/init.d/
sudo chmod 777 test.sh
sudo update-rc.d test.sh defaults  98

其中 98 为开机序号，范围0-99，数字越大，开机启动的顺序越慢。
修改之后，重启即可成功

sudo  reboot

3.3 效果查看

开机重启后，可以查看每次开机都有 ~/test_result.txt 文件产生，查看文件

sky@ubuntu:~$ cat test_result.txt 
just for a automatic script

3.4 卸载方法

cd /etc/init.d
sudo update-rc.d -f test remove

4 延伸说明

4.1 自启动脚本都有哪些

系统自带的启动脚本以及顺序，都存放于 /etc/rcN.d/
查看系统使用的是哪个rc 文件夹

sky@ubuntu:~$ runlevel 
N 5

说明采用的是 rc5.d 文件夹，查看文件夹里面的内容
