I've used this command to find the IP of the server. Can someone explain what the command means? I want to learn.
So far I know: "wget" is a free utility for non-interactive download of files from the Web [http://linux.about.com/od/commands/l/blcmdl1_wget.htm]
"-O" Writes the documents to File
"-q" quiet (no output)
But why use that "-" in between?
