How to resume screen?
The wording is a little unlucky - this happens because there still is a screen
session attached to 14313.pts-18.b-dev03
and you cannot simply "resume" a non-detached session. You need to use the -x
option in addition to attaching to this session with a second screen
instance (or, alternatively, detach the existing session first):
-x
Attach to a not detached screen session. (Multi display mode).
$ screen -xr 14313
If you wish to detach the first session instead:
-d -r
Reattach a session and if necessary detach it first.
$ screen -dr 14313
