Description of the problem including expected versus actual behavior:

packetbeat.sh won't work if the filename contains spaces. This is due to the $@ in the bash script. Quoting does not help.

Steps to reproduce:
sudo packetbeat.sh -e -c /etc/packetbeat/packetbeat.yml -t -I DNS01\ -\ C3-.pcap -d "publish"
