1.建立shell啟動指令碼test

2.將啟動指令碼複製到 /etc/init.d 目錄下

3.設定指令碼檔案許可權

sudo chmod 755 /etc/init.d/test

4.設定指令碼啟動

sudo update-rc.d test defaults 95   //95 為啟動優先順序，越小優先順序越高

// 執行後輸出資訊

update-rc.d: warning: /etc/init.d/test missing LSB information
update-rc.d: see <http://wiki.debian.org/LSBInitScripts>
  Adding system startup for /etc/init.d/test ...
    /etc/rc0.d/K95test -> ../init.d/test
    /etc/rc1.d/K95test -> ../init.d/test
    /etc/rc6.d/K95test -> ../init.d/test
    /etc/rc2.d/S95test -> ../init.d/test
    /etc/rc3.d/S95test -> ../init.d/test
    /etc/rc4.d/S95test -> ../init.d/test
    /etc/rc5.d/S95test -> ../init.d/test

4.解除安裝啟動指令碼

sudo update-rc.d -f test remove
