I need help using rtmpdump. I kinda really suck with command line stuff. I know how to use all the other rtmp programs but, i suck with rtmpdump.

I looked at the how do you use rtmpdump instructions and i kinda don't know what to do. I got the program downloaded extracted brought up command line thing how do i get it started?

i have some streaming url's i'm trying to record do i type the entire thing like it says

rtmpdump basic usage
Code:

rtmpdump -r "rtmp://host/dir/file.flv" -o filename.flv
