我没有使用服务截取屏幕截图

我正在使用 shell 脚本，我想在系统启动时自动运行该脚本开启/重启无需打开任何应用程序。

这是我的script.sh文件：

while sleep 5 
do
scrot 'myimage.png' -e 'mv $f ~/Desktop/'
done

测试.service文件：

[Unit]
Description=My Shell Script
   
[Service]
ExecStart=/home/chirag/tracker-ror/script.sh
    
[Install]
WantedBy=multi-user.target

> sudo systemctl status test.service

    ● test.service - My Shell Script
