   curl -s -X POST http://ip.ad.dr.ess/incoming/ \ -H 'Tus-Resumable: 1.0.0' \ -H "Upload-Metadata: filename $(printf %s "$(basename "$FILE")" | base64)" \ -H "Upload-Length: $(stat -c%s "$FILE")" \ -H "Content-Type: application/offset+octet-stream" \ --data-binary @"$FILE" -o /dev/null -w "%{http_code}\n"
