This question already has an answer here:
Let's assume I run putty on windows and connect to Debian Jessie remotely. I run Midnight commander, and run long term task. Than got power loss on Windows, so putty connection is lost.
Of course I should use screen, but i forgot.
After reconnection I can see mc in
1864 pts/3 S+ 0:10 mc
Is there a way to reconnect to this process? (And is it running?)
