nohup is a very handy command... Another very useful utility for this is
called screen.  Once you start screen, you've basically got a set of
terminals within a terminal & you can even "detach" from screen, log
out, and come back later & reattach to your session.  Kind of like
interactive nohup for your entire session. just type 'screen -R' to
start it (the -R will reattach if possible, or just create a new one).

Some basic screen commands (each begins with a CTRL+a):
ctrl+a c : new session
ctrl+a 0 ... 9 : switch between sessions
ctrl+a ctrl+a : bounce between two sessions
ctrl+a w : list open sessions
ctrl+a d : detach from screen; sessions continue to run, even if you log
out.

when you log back in, start screen with -R to reattach to your session. 
man screen for even more cool stuff.
