For curiosity, I wanted to read a GNU screen session's named pipe.
$ screen -ls There is a screen on: 59750.hello (Detached) 1 Socket in /var/run/screen/S-gergely.
And indeed there is a named pipe:
S-gergely $ ls -l összesen 4 prw-------. 1 gergely gergely 0 nov 21 11.06 59750.hello
I tried to read it with
cat and other things to no avail.
(Detached) mean that there is no flux of data through this named pipe? Only when the screen is active?
UPDATE: it does not work even when that screen is active
Can I read the data with some standard Unix command-line tool?
