How can you verify that the server is running using the command line?

You can verify that the server is running by using the curl command or by checking the process list. Here are two methods:

Method 1: Using curl

If your server is running on localhost and the default port (e.g., 5000 for Flask), you can use the following command:

curl http://localhost:5000

If the server is running, you should receive a response from the server.

Method 2: Checking the Process List

You can also check if the server process is running by using the ps command:

ps aux | grep flask

This will list all processes related to Flask. If you see your Flask application in the output, it means the server is running.
