command to display system load?

[Deephay <tudoxxx@gmail.com>]

Greetings all,

  I am wondering that which command can display some information about the system load
like this:
 07:17:25 up  9:07,  6 users,  load average: 0.42, 0.41, 0.30
(I got this when I tried to overwrite a file with vim)
thx!
