really needing help

[luishi07]

im having a big problem. Im using a script with wget to retrieve some files from a server.
Since the files are getting bigger and i must retrieve them every hour more or less i need to know how can i modify the script (this script is being launched by a cronfile every hour) so it detects if the wget is already running, if so dont launch it again and exit but if wget is not running then launch it
I think its just an if but the deal is that i dont know how to check if the wget app is running by command line (i can see it with the nice gui interface called system monitor).
Im using ubuntu 7.04.
Thanks a lot for the help
