Bash 基于docker输出中的url启动浏览器

我正在使用cmd/powershell启动docker映像，docker映像将启动Jupyter lab，该实验室的输出中有一个URL，我希望复制该URL，然后使用该URL启动默认浏览器

docker run-p 8888:8888-it“jupyter/lab”

上述命令的输出包含一些带有URL的文本：

[I 18:57:25.428 LabApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret

    To access the notebook, open this file in a browser:
        file:///root/.local/share/jupyter/runtime/nbserver-1-open.html
    Or copy and paste one of these URLs:
        http://(811378b194e4 or 127.0.0.1):8888/?token=9c260361ba75b9a2a70ad1e9eaa12155d628700382055274

我想启动带有URL的浏览器：

http://127.0.0.1:8888/?token=9c260361ba75b9a2a70ad1e9eaa12155d628700382055274

我尝试将输出写入日志文件，然后解析日志文件中的url，并使用start cmd在浏览器中启动url，但似乎无法获取url，docker命令没有返回，它正在运行服务器

docker run -p 8888:8888 -it "jupyter/lab" > docker.log
URL=
start $URL
