# `--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.
