I'm using screen to keep some applications open over a remote SSH
connection that sometimes is killed. What I would like to do, is to
somehow find out whether I am logged in (attached) or disconnected
from the screen session.
Reason is that I want procmail to send incoming mail to my BlackBerry
if I'm disconnected, but NOT do that when I'm SSH-ing into my Pine
session.
I don't know how to achieve that, but perhaps there's a different
approach to the problem -- such as always forwarding all mail to an IMAP
server that you can access from both the blackberry and from pine.
The screen-socket has execute permissions when attached, and none when
detached, like this:
attached:
ls -l /tmp/uscreens/S-peder/4598.irc
prwx------ 1 peder peder 0 Oct 14 00:00 /tmp/uscreens/S-peder/4598.irc
detached:
ls -l /tmp/uscreens/S-peder/4598.irc
prw------- 1 peder peder 0 Oct 14 07:06 /tmp/uscreens/S-peder/4598.irc
Guess you can test for that i procmail by something like:
:0c
*? perl -e 'exit ! grep { (stat $_)[2] & 0100 } </tmp/uscreens/S-peder/*>'
