`--range`

Retrieve a byte range (i.e. a partial document) from an HTTP/1.1, FTP or SFTP server or a local FILE. Ranges can be specified in a number of ways.

0-499

specifies the first 500 bytes

500-999

specifies the second 500 bytes

-500

specifies the last 500 bytes

9500-

specifies the bytes from offset 9500 and forward

0-0,-1

specifies the first and last byte only(*)(HTTP)

100-199,500-599

specifies two separate 100-byte ranges(*) (HTTP)

(*) = NOTE that these make the server reply with a multipart response, which is returned as-is by curl. Parsing or otherwise transforming this response is the responsibility of the caller.

Only digit characters (0-9) are valid in the 'start' and 'stop' fields of the 'start-stop' range syntax. If a non-digit character is given in the range, the server's response is unspecified, depending on the server's configuration.

Many HTTP/1.1 servers do not have this feature enabled, so that when you attempt to get a range, curl instead gets the whole document.

FTP and SFTP range downloads only support the simple 'start-stop' syntax (optionally with one of the numbers omitted). FTP use depends on the extended FTP command SIZE.
