非阻塞命令处理

我正在尝试运行以下命令:

! sudo chromium-browser --no-sandbox www.google.com

通过命令行

! sudo chromium浏览器——无沙箱www.google.com

并添加到sh脚本文件中,其中输出为:

sudo ./ruunn.sh
 --disable-quic --enable-tcp-fast-open --disable-gpu-compositing --ppapi-flash-path=/usr/lib/chromium-browser/libpepflashplayer.so --ppapi-flash-args=enable_stagevideo_auto=0 --ppapi-flash-version=

浏览器成功打开。问题是python脚本没有返回,因此无法执行其他命令。有没有一种不阻塞地执行命令的方法?我正在jupyter笔记本中执行这些命令。
