Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

I'm doing some stuff with Facebooks FQL at the moment, and I'm using curl on the command line to test some of the responses of it. I'm also using export to keep the params seperated for easy editing. But I'm doing something wrong, and I can't see what.

This produces a perfectly fine result (even with the export):

export FB_TOKEN="the_access_token"
curl -F access_token=$FB_TOKEN -F query="SELECT first_name FROM user WHERE uid=12345678910123" https://api.facebook.com/method/fql.query

But this does mess up:

export FB_TOKEN="the_access_token"
export FB_QUERY="SELECT first_name FROM user WHERE uid=12345678910123"
curl -F access_token=$FB_TOKEN -F query=$FB_QUERY https://api.facebook.com/method/fql.query

and produces the following output:

curl: (6) Couldn't resolve host 'first_name'
curl: (6) Couldn't resolve host 'FROM'
curl: (6) Couldn't resolve host 'user'
curl: (6) Couldn't resolve host 'WHERE'
curl: (6) Couldn't resolve host 'uid=100001273321556'
<?xml version="1.0" encoding="UTF-8"?>
(...further response that the request was invalid here...)

I don't see anything I forgot to escape. Why does curl insist on interpreting these as hosts?

Used software versions:
curl 7.21.3; bash 4.2.8(1)

FB_QUERY must be quoted:

curl -F access_token=$FB_TOKEN -F query="$FB_QUERY" https://api.facebook.com/method/fql.query
