1 Long: data
2 Short: d
3 Arg: <data>

10 Sends the specified data in a POST request to the HTTP server, in the same way
11 that a browser does when a user has filled in an HTML form and presses the
12 submit button. This will cause curl to pass the data to the server using the
13 content-type application/x-www-form-urlencoded.  Compare to --form.
14 
15 --data-raw is almost the same but does not have a special interpretation of
16 the @ character. To post data purely binary, you should instead use the
17 --data-binary option.  To URL-encode the value of a form field you may use
18 --data-urlencode.
19 
20 If any of these options is used more than once on the same command line, the
21 data pieces specified will be merged together with a separating
22 &-symbol. Thus, using '-d name=daniel -d skill=lousy' would generate a post
23 chunk that looks like \&'name=daniel&skill=lousy'.
24 
25 If you start the data with the letter @, the rest should be a file name to
26 read the data from, or - if you want curl to read the data from stdin. Posting
27 data from a file named \&'foobar' would thus be done with --data @foobar. When
28 --data is told to read from a file like that, carriage returns and newlines
29 will be stripped out. If you don't want the @ character to have a special
30 interpretation use --data-raw instead.
