I see curl supports partial downloads

-r, --range RANGE   Retrieve only the bytes within a range

Example

curl -r 0-99 http://foo.com/bar.mp4

However, can wget accomplish something similar?

回答1:

Unfortunately wget doesn't have this feature(at least with my GNU Wget 1.10.2 (Red Hat modified)), which is very annoying. You can send the Range header with HTTP request, but doesn't work.

wget "http://www.example.com"  -c --header="Range: bytes=0-99"

It returns

HTTP request sent, awaiting response... 206 Partial Content
Giving up.

It seemed that the wget had the proper response, but strangely, it didn't finish it. For example with verbose mode output:

HTTP request sent, awaiting response... 
  HTTP/1.0 206 Partial Content
  Accept-Ranges: bytes
  Cache-Control: max-age=604800
  Content-Range: bytes 0-99/1270
  Content-Type: text/html
