Write output to instead of stdout. If you are using {} or [] to fetch multiple documents, you should quote the URL and you can use ‘#’ followed by a number in the specifier. That variable is replaced with the current string for the URL being fetched. Like in:

curl "http://{one,two}.example.com" -o "file_#1.txt"

or use several variables like:

curl "http://{site,host}.host[1-5].example" -o "#1_#2"

You may use this option as many times as the number of URLs you have. For example, if you specify two URLs on the same command line, you can use it like this:

curl -o aa example.com -o bb example.net

and the order of the -o options and the URLs does not matter, just that the first -o is for the first URL and so on, so the above command line can also be written as

curl example.com example.net -o aa -o bb

See also the --create-dirs option to create the local directories dynamically. Specifying the output as ‘-’ (a single dash) passes the output to stdout.

To suppress response bodies, you can redirect output to /dev/null:

curl example.com -o /dev/null

Or for Windows:

curl example.com -o nul
