How can I exit jekyll's site local preview mode in GitShell

Question

After evaluate the Jekyll serve, I can see the site in localhost:4000

but how to exit the preview mode?

Of course I can close the GitShell and reopen it to cd into directory and re-build to preview, but boring.

Answer 1

What do you mean by "preview mode"?

Do you just want Ctrl + C to terminate? If I understand you correctly, this has nothing to do with Jekyll I reckon, it's a basic operation the command line interface.
