how to monitor how much memory, cpu is used by an instance of a program/script running in linux?

Question

I am on an ubuntu server, so I only have SSH terminal.

I would like to monitor how much memory and CPU something like

Jruby test.rb

is using.

Is it possible to monitor how much bandwith a process consumes? for example

rtorrent test.torrent

You might want to add "linux" as a tag, as this is not at all Ubuntu specific or server specific.

For starters.

vmstat
procinfo -D
top
htop
pstree

ps -ef | grep test.rb
will give some info too.

Yes, there are bandwidth monitors out there, iotop for one.

http://bhami.com/rosetta.html is always a decent starting point.
