How to realize the function of resuming File at breakpoint by Linux
What is a breakpoint continuation?

In fact, the breakpoint continuation is literally meant to continue the transmission at the disconnect point of the download, without having to start from scratch. So after understanding the core of the breakpoint continuation, I found that it is actually very simple, and the key lies in the grasp of the transmission breakpoint. I drew a simple diagram of my own understanding:
Linux breakpoint continuation file
When uploading and downloading files in the Linux system, it is easy to disconnect or transfer large files. How to continue the transfer after disconnection does not have to start over. Here we can use Linux's rsync.
