I wanted to create a screen socket with a specific name, and
later be able to kill that particular window. I create the window like
this:
screen -S arduino /dev/ttyACM0
I expected to be able to kill it like this:
screen -p arduino -X kill
But this doesn't work, all that happens is I get an inverted text
message at the bottom of the window like this:
-X: kill: window required
After some google I find that this works:
screen -S arduino -X kill
Here is the description of the -S option in the man page:
-S sessionname
When creating a new session, this option can be used to specify a
meaningful name for the session. This name identifies the session
for "screen -list" and "screen -r" actions. It substitutes the
default [tty.host] suffix.
Here is the description of the -p option:
-p number_or_name
Preselect a window. This is useful when you want to reattach to a
specific window or you want to send a command via the "-X" option
to a specific window. As with screens select command, "-" selects
the blank window. As a special case for reattach, "=" brings up
the windowlist on the blank window.
So you can see why I want to use -p, not -S. I think its still worth keeping
the man page up to date despite google. I don't know how git works for
this project or what the true semantics of -S and -p options are or I could
do this myself. If anyone wants to tell me what these option descriptions
should be I'll try to get them into git.
Thanks,
Britton
