Re: screen script

[Nick Atzert]

Oh no I'm not launching 20k scripts at once. At most I'll do about 100 at one time. I usually have to do this 3 or 4 times over the course of one day at work though. It's just tedious and I'm trying to automate as much as possible.

I will definitely check out some of your guys suggestions. Thanks!

What about scripting the .screenrc processing, or launching them
dynamically ? From within screen, you can spawn a new session, with the
same command suggested by Alan Young :

for SERVER in `cat servers.list`
do
        screen -t "$SERVER" 0 /bin/bash -c "whatever you want on $SERVER"
done


By the way, I'm not sure screen is the most convenient/effective way to
launch 20k scripts simultaneously.
