> In SSH sessions, when you run vim, top, etc., the displayed data overwrites
> the recent rollback buffer.
> !image-2022-07-06-14-08-38-966.png!
> ⬆️ The image above shows the rollback buffer before I used vim, when the
> rollback buffer should hold the data from ll.
> !image-2022-07-06-14-11-02-204.png!
> ⬆️ However, after the vim command is used and the exit, the echo generated
> by ll command in the rollback buffer has been overwritten by the vim command.
> I know that the last page of data should be preserved after exiting using
> vim, but the data in the previous rollback buffer should not be lost, and I
> feel that this part of the processing like secureCRT is what we want.
> !image-2022-07-06-14-18-23-551.png!
> ⬆️ Just like this, after I use the vim command and exit, the previous ll
> command output will still exist, and the vim command will retain the state of
> the last screen before exiting.
