Sounds like a big overkill for trivial screen -wipe command.

[Comment 4 Neil Bothwick 2006-10-10 15:58:10 UTC]

screen -wipe is insufficient as it only removes screens owned by the user running it, root in this case.

To remove screens belonging to all owners, you need

find /var/run/screen/ -type p | sed s:/var/run/screen/S-:: | xargs --no-run-if-empty screen -wipe

Running it from local.start should be enough, a separate script for a single command line seems OTT.

Sorry for my english! 

Yes the idea is remove all screens deads on start up

[Comment 6 Sven Wegener 2006-10-12 14:44:36 UTC]

You can't use xargs with screen this way, as screen requires stdin to be a tty. And you need -n 1 as screen will only wipe the first argument. Using rm -f /var/run/screen/S-*/* is bad, as it will remove active sessions and local.start is too late, as some init scripts use screen too launch a daemon in background. I agree with Jakub that it's too much hassle for a single command.
