If you are downloading a big file (or even a small one) and the connection breaks or times out, use this command in order to RESUME the download where it failed, instead of having to start downloading from the beginning. This is a real win for downloading debian ISO images over a buggy DSL modem.

Take the partially downloaded file and cat it into the STDIN of curl, as shown. Then use the "-C -" option followed by the URL of the file you were originally downloading.

Know a better way?

This would be useful if all web browsers used the same partial download format.

This one works best: "curl -C - -o partially_downloaded_file" - and here's the trick you usually need to go along with it

a) Open your browser to the file you want to download

b) right-click on pick "inspect element"

c) click on the "network" tab that shows up

d) click (left) to start downloading the file again - when the file-save dialogue comes up, cancel it.

e) go back to the network tab, right-click on the last entry, and choose "copy as cURL"

*) You now have a new download URL with all the login/authorization/cookies/etc stuff properly included. If you use Linux, replace all " with ' before use.
