Download File from Google Docs using wget

[style-sheets]

Hi guys,

I'm trying to download a file from google docs using wget, I was able to login & get the download link, but when I try to download it, both curl and wget fail.

I used this bash code:

#!/bin/bash

# Login to google docs & get auth token
sid=$(curl -s https://www.google.com/accounts/ClientLogin -d Email=us...@email.com -d Passwd=my_password -d accountType=GOOGLE -d service=writely -d Gdata-version=3.0)
auth_token=${sid:764:374}

document_id=0BxONkKiBZQq6ZmNjN2RjZjYtMjZhYi00MjRiLWJmN2YtNGM2ZjE4YWQ5Mzg0

# Get download link (already have the file ID)
download_url=$(curl -s --header "Authorization: GoogleLogin auth=${auth_token}" --header "GData-Version: 3.0" "http://docs.google.com/feeds/default/private/full/${document_id}")

if [[ $download_url =~ "src='([^']+)" ]]; then
        n=${#BASH_REMATCH[*]}
        if [[ $n -ge 1 ]]; then
                download_url=${BASH_REMATCH[1]}
        fi
else
        echo "No match found"
fi

# Download file & save it to disk
wget --output-document="/full/path/file.zip" --tries=1 --server-response --connect-timeout=20 --user-agent="Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6) Gecko/20061201 Firefox/2.0.0.6 (Ubuntu-feisty)" --verbose --debug --no-cache --header "Authorization: GoogleLogin auth=${auth_token}" --header "GData-Version: 3.0" ${download_url}

The last wget call returns this error message:

The same error happen when I use curl.

The URL format for the download link looks correct to me (but since it's dynamic I can't just reuse it to see exactly what's wrong):

I googled "wget Closed fd 4" and it seems this is related to authentication, which is strange since I'm certain I was successfully logged in.

So I tried these operations, just to make sure:

1.  Login
2.  Get the list of folders & files
3.  Get the download link for a file in particular
4.  Download the file.

Only the last operation (download the file) failed, if it was a session problem, failure would've happened sooner.

Also, I don't think that the issue is happening because I used wget instead of curl (I used curl everywhere except when downloading the file), in fact, at first used this curl syntax before trying with wget (both methods failed):

ANY help would be greatly appreciated,

Thanks in advance!
