Screen

Screen is a 'virtual terminal' inside your normal terminal connnection. I.e. you can make a ssh,
console or serial login and inside it establish a 'screen' connection.

At any later point you can 'reconnect' or take over that screen from another login.

This way you can manage processes which either take a very long time (during which you 
may loose connection) or reconnect to a task from a different location point you can 
'reconnect' or take over that screen from another login.

-	install with

		pkg_add -r screen

-	start
		screen

-	see what terminals there are

		screen -ls

-	reconnect to a to a terminal you 'lost'

		screen -r

Example procedue:

->	ssh mymachine
	Password:
	su root
	# screen
	  # cd  /usr/svn/master
	  # sh makemaster.sh
	  ....

-> during this 5-10 hour process you loose the connection; or move to another
   machine somewhere. From this new machine do:

	ssh mymachine
	screen -r
OR
	screen -ls
	screen -r 1672

Where 1672 is the pid/id of the process you lost connection with. Alternatively
you can also press 'ctrl-A', 'D' to detatch from a 'screen' in a manner which allows
you to reconnect later.
