How to copy and update new file on google drive?

I have a file.txt that I want to upload to google. I can upload it using rclone copy. But then I made some changes to the file(new dates, new size, new hash). If I use rclone copy, does it update the file in the cloud? From the documentation it doesnt seems it does.

Thanks.

If rclone figures out it has changed, then it will upload it again. Add -v to the command line to see what files rclone uploads.
