# GLOBBING You can specify multiple URLs or parts of URLs by writing lists within braces or ranges within brackets. We call this "globbing". Provide a list with three different names like this: https://fun.example/{one,two,three}.jpg sftp://{one,two,three}.example/README Do sequences of alphanumeric series by using [] as in: ftp://ftp.example.com/file[1-100].txt With leading zeroes: ftp://ftp.example.com/file[001-100].txt With letters through the alphabet: ftp://ftp.example.com/file[a-z].txt Nested sequences are not supported, but you can use several ones next to each other: https://example.com/archive[1996-1999]/vol[1-4]/part{a,b,c}.html You can specify a step counter for the ranges to get every Nth number or letter: https://example.com/file[1-100:10].txt https://example.com/file[a-z:2].txt When using [] or {} sequences when invoked from a command line prompt, you probably have to put the full URL within double quotes to avoid the shell from interfering with it. This also goes for other characters treated special, like for example '&', '?' and '*'. The separate globbing components can be referenced in the --output option to allow pieces to be reused in the target filename. Starting in curl 8.21.0, the separate globbing parts can be named and referenced by their names. The case sensitive alphanumeric name is set enclosed within angle brackets after the opening character. Examples: https://fun.example/{one,two,three}.jpg ftp://ftp.example.com/file[1-100].txt Setting the same glob name twice is an error. Switch off globbing with --globoff.
