Checking on terminal window remotely [duplicate]

I have something working on a computer which is displaying its results (in this case, a very large rsync displaying the files as it goes, but other stuff happens), is there any way i can check on it's progress from a remote ssh connection, or do i have to wait until i can get back to that machine? I know how to check for when it's finished, I'd just like to know where it's at now)
