== HowTo Continue to Retrieve A Partially-Downloaded File With: "wget" ==
The "'''wget'''" command has a "'''--continue'''" option for downloading a file that has not been completely retrieved. This is a <u>handly</u> option to use when dealing with large file sizes (i.e. greater than 500MBs) and the connection has stopped. Restarting the download with the "'''--continue'''" option will continue the retrieval process from the last byte that was downloaded.
