set environment variable in ruby and pass it to shell

I am running a sinatra web app that gets a file (upload) from the user. It then transfers the file to a server via scp. Can I grab the filename from the params Hash and set it as an environment variable and pass it to the scp command. Below is a snippet of my code.

ENV[file] = params['arne_site_file'][:filename]
transfer = `scp -i /opt/zabbix-proxy/etc/.ssh/id_rsa $file [email protected]:/home/zabbix/ARNE_5216_files`

Params Hash is - 

{
"arne_site_file" => {
    :filename => "ARNE_SITE__BB5216_L16B_936441_HWY_54_A.xml"
},
        "submit" => "Validate File"
 }

Found the solution. It turns out I was missing quotes. ENV['file'] = params['arne_site_file'][:filename]. This resolved the issue. Great to know that env variables can be set by Ruby for other bash scripts to access.
