transfer a URL
|
-s, --silent
Silent or quiet mode. Don't show progress meter or error messages. Makes Curl mute.
|
-S, --show-error
When used with -s it makes curl show an error message if it fails.
|
-A, --user-agent <agent string>
(HTTP) Specify the User-Agent string to send to the HTTP server. Some badly done CGIs fail if this
field isn't set to "Mozilla/4.0". To encode blanks in the string, surround the string with single
quote marks. This can also be set with the -H, --header option of course.
If this option is set more than once, the last one will be the one that's used.
|
-o, --output <file>
Write output to <file> instead of stdout. If you are using {} or [] to fetch multiple documents,
you can use '#' followed by a number in the <file> specifier. That variable will be replaced with
the current string for the URL being fetched. Like in:
curl http://{one,two}.site.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.
|
-m, --max-time <seconds>
Maximum time in seconds that you allow the whole operation to take. This is useful for preventing
your batch jobs from hanging for hours due to slow networks or links going down. See also the
--connect-timeout option.
If this option is used several times, the last one will be used.
|
-w, --write-out <format>
Defines what to display on stdout after a completed and successful operation. The format is a
string that may contain plain text mixed with any number of variables. The string can be specified
as "string", to get read from a particular file you specify it "@filename" and to tell curl to
read the format from stdin you write "@-".
