From Entropy.ch:
Here’s a little terminal command I use to repeatedly attempt to download a file. This is useful if the transfer aborts frequently or if the server is busy:
The while/do/done loop keeps calling curl, with pauses of 10 seconds. curl will keep returning a failure exit code, which is what keeps the while loop going if inverted with the ! (logical not) operator. The -C - flag tells curl to continue at the last byte position.
