-o, --output
Write output to instead of stdout. If you are using {} or [] to fetch multiple documents, you can use '#' followed by a number in the specifier. That variable will be 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].com -o "#1_#2"
You may use this option as many times as the number of URLs you have.
See also the --create-dirs option to create the local directories dynamically. Specifying the output as '-' (a single dash) will force the output to be done to stdout.
