| 16 | Write output to <file> instead of stdout. If you are using {} or [] to fetch |
| 17 | multiple documents, you should quote the URL and you can use '#' followed by a |
| 18 | number in the <file> specifier. That variable will be replaced with the current |
| 19 | string for the URL being fetched. Like in: |
| 20 | |
| 21 | curl "http://{one,two}.example.com" -o "file_#1.txt" |
| 22 | |
| 23 | or use several variables like: |
| 24 | |
| 25 | curl "http://{site,host}.host[1-5].com" -o "#1_#2" |
| 26 | |
| 27 | You may use this option as many times as the number of URLs you have. For |
| 28 | example, if you specify two URLs on the same command line, you can use it like |
| 29 | this: |
| 30 | |
| 31 | curl -o aa example.com -o bb example.net |
| 32 | |
| 33 | and the order of the -o options and the URLs does not matter, just that the |
| 34 | first -o is for the first URL and so on, so the above command line can also be |
| 35 | written as |
| 36 | |
| 37 | curl example.com example.net -o aa -o bb |
| 38 | |
| 39 | See also the --create-dirs option to create the local directories |
| 40 | dynamically. Specifying the output as '-' (a single dash) will force the |
| 41 | output to be done to stdout. |
| 42 | |
| 43 | To suppress response bodies, you can redirect output to /dev/null: |
| 44 | |
| 45 | curl example.com -o /dev/null |
| 46 | |
| 47 | Or for Windows use nul: |
| 48 | |
| 49 | curl example.com -o nul |
