That is a very big and complicated command. I would try and unwrap that a little, not jam everything on one line.
Also, you can't jam multiple lines of text in a variable and expect them to work right. Quoting them is a bit of a hassle. Save it in a file instead -- that makes it easy to use in a loop or transfer into anything else.
How do I evaluate the result of a command assigned to a variable??
Example:
var1=`cmd`
rc=$?
rc will be the result of the assignment rather than cmd since it executes after. How do I evaluate the result of the command itself?

libcurl(3) libcurl easy interface libcurl(3)NAME
libcurl-easy - easy interface overview
DESCRIPTION
When using libcurl's "easy" interface you init your session and get a handle (often referred to as an "easy handle"), which you use as
input to the easy interface functions you use. Use curl_easy_init(3) to get the handle.
You continue by setting all the options you want in the upcoming transfer, the most important among them is the URL itself (you can't
transfer anything without a specified URL as you may have figured out yourself). You might want to set some callbacks as well that will be
called from the library when data is available etc. curl_easy_setopt(3) is used for all this.
When all is setup, you tell libcurl to perform the transfer using curl_easy_perform(3). It will then do the entire operation and won't
return until it is done (successfully or not).
After the transfer has been made, you can set new options and make another transfer, or if you're done, cleanup the session by calling
curl_easy_cleanup(3). If you want persistent connections, you don't cleanup immediately, but instead run ahead and perform other transfers
using the same easy handle.
