How to print the bytes while the file is being downloaded ? -golang

Question

I\'m wondering if it\'s possible to count and print the number of bytes downloaded while the file is being downloaded.

out, err := os.Create(\"file.txt\")
    d

The grab Go package implements progress updates (and many other features) for file downloads.

An example of printing progress updates while a download is in process is included in the following walkthrough: http://cavaliercoder.com/blog/downloading-large-files-in-go.html

You can basically call grab.GetAsync which downloads in a new Go routine and then monitor the BytesTransferred or Progress of the returned grab.Response from the calling thread.
