VERBOSE / DEBUG

  If curl fails where it isn't supposed to, if the servers don't let you

  in, if you can't understand the responses: use the -v flag to get VERBOSE

  fetching. Curl will output lots of info and all data it sends and

  receives in order to let the user see all client-server interaction.

  If curl fails where it isn't supposed to, if the servers don't let you in,

  if you can't understand the responses: use the -v flag to get verbose

  fetching. Curl will output lots of info and what it sends and receives in

  order to let the user see all client-server interaction (but it won't show

  you the actual data).

        curl -v ftp://ftp.upload.com/

  To get even more details and information on what curl does, try using the

  --trace or --trace-ascii options with a given file name to log to, like

  this:

        curl --trace trace.txt www.haxx.se

DETAILED INFORMATION

  Different protocols provide different ways of getting detailed information

        curl -b headers www.example.com

  While saving headers to a file is a working way to store cookies, it is

  however error-prone and not the prefered way to do this. Instead, make curl

  save the incoming cookies using the well-known netscape cookie format like

  this:

        curl -c cookies.txt www.example.com

  Note that by specifying -b you enable the "cookie awareness" and with -L

  you can make curl follow a location: (which often is used in combination

  with cookies). So that if a site sends cookies and a location, you can

  stored cookies which match the request as it follows the location.  The

  file "empty.txt" may be a non-existant file.

  Alas, to both read and write cookies from a netscape cookie file, you can

  set both -b and -c to use the same file:

        curl -b cookies.txt -c cookies.txt www.example.com

PROGRESS METER

  Forcing curl not to transfer data faster than a given rate is also possible,

  which might be useful if you're using a limited bandwidth connection and you

  don't want your transfer to use all of it.

  don't want your transfer to use all of it (sometimes referred to as

  "bandwith throttle").

  Make curl transfer data no faster than 10 kilobytes per second:

        curl -T upload --limit-rate 1M ftp://uploadshereplease.com

  When using the --limit-rate option, the transfer rate is regulated on a

  per-second basis, which will cause the total transfer speed to become lower

  than the given number. Sometimes of course substantially lower, if your

  transfer stalls during periods.

CONFIG FILE

  Curl automatically tries to read the .curlrc file (or _curlrc file on win32
