[solved] Pickup output of a running process

Hi all,

When ssh'ing to a box i want to emerge a program and close the connection because leaving the connection open is out of the question.
so i do

#emerge "somestuff"&

and then i close the ssh connection

How can i reconnect to that box and pickup the output of that emerge.
I can see it's busy because the output of "top" and ps -A gives me running emerge processes etc,...

Anyone with tips or better approaches?

Thanks in advance
Greetings J

That's a possibility, hmm

is there a way in ssh to log off, leave the session active and pick it up later on ?

You could use 'screen'.

ssh to the server, start screen, start emerging or whatever you want to do, then detatch from the session with ctrl-a, ctrl-d. Now you can close the ssh-connection, and when you have reconnected just type "screen -r", and it will reattach to the session you detatched from earlier.
Of course you need to "emerge screen" first if you don't have it.
