Fragment

A URL may contain an anchor, also known as a fragment, which is written with apound sign and string at the end of the URL. Like for examplehttp://example.com/foo.html#here-it-is. That fragment part, everything fromthe pound/hash sign to the end of the URL, is only intended for local use andis not sent over the network. curl simply strips that data off and discardsit.

A range trick

A practical way to exploit the fact that the fragment is not sent over thewire, is to use that field for ranges if you want to use the same URL manytimes on the command line.

For example, download this URL twenty times:

curl "https://example.com/#[1-20]"
