Screen is a handy little thing that lets you run an extra persistent console in the background which stays active after you disconnect.
However, scrolling back up the screen buffer is a tad more tricky.
After using it on and off for a few years, I've finally run into the need to scroll up to see what's in the buffer.
To do that:
- Press Ctrl+A
- then [
- And use J or K to move up and down (or the arrow keys)
Enjoy!
