To instead 22 | download it as `hodor.jpg`, you can use the `--name` argument: 23 | 24 | $ make-prefetch.py --name hodor.jpg http://i.imgur.com/YAUeUOG.jpg 25 | 26 | This will output the same prefetch statement as before, but it will be 27 | downloaded as `hodor.jpg` on the client. 28 | 29 | prefetch hodor.jpg sha1:ce842e0af799f2ba476511c8fbfdc3bf89612dd0 size:57656 http://i.imgur.com/YAUeUOG.jpg

Hodor](http://i.imgur.com/YAUeUOG.jpg) and you want to create a 35 | prefetch statement for it. 36 | 37 | To do this, run `make-prefetch.py` on the file to generate a prefetch statement: 38 | 39 | $ make-prefetch.py hodor.jpg 40 | 41 | This will output a prefetch statement with `http://REPLACEME` as the URL: 42 | 43 | prefetch hodor.jpg sha1:ce842e0af799f2ba476511c8fbfdc3bf89612dd0 size:57656

make-prefetch.py hodor.jpg --url http://example.com/winterfell/hodor.jpg 48 | 49 | This will output the same prefetch statement as before, but the URL will be 50 |
