I'm using curl with curl -v https://example.com
and at the end it says * Connection #0 to host example.com left intact. What does that mean?

Human connection is a deep bond that's formed between people when they feel seen and valued. During an authentic human connection, people exchange positive energy with one another and build trust. Human connection makes you feel heard and understood and gives you a sense of belonging.

The root is the Latin connexionem, "a binding or joining together." Definitions of connection.
Adding a header "Connection: close" to your CURL command should solve the problem:
curl -v -H "Connection: close" https://example.com
Explanation can be found in this article:
Why is the connection left intact ?
The connection is left intact, because the server allowed it to stay open and CURL no need to close it after you receive the response for the request sent. That’s why the requests return ‘Connection: keep-alive‘ headers when you expect ‘Connection:close‘
If you wanted to close the connection, then you could send CURL request with ‘Connection: close‘ as shown below and you could see ‘* Closing connection 0‘ in the response.
I hope the article https://www.sneppets.com/software/connection-0-to-host-localhost-left-intact/ helps you solve your problem.

Short answer: it doesn't mean anything, when you just request one URL. After curl is finished and the process exits, the connection is not left intact anywhere despite the misleading message; it is closed just like you'd expect.
The connection is only reused if you fetch multiple URLs in the same curl invocation. In that case it's a good thing, and you shouldn't need to force the connection to close, unless you're debugging connection issues.
(I too went looking for answers, when I wanted to check that curl doesn't somehow keep the connection open in the background of my shell. It doesn't.)
