Let's just run this in the office and see what happens...

shellshock.sh

#!/usr/bin/env bash

video_url='https://www.youtube.com/watch?v=dQw4w9WgXcQ'

exists() {
  which "$1" &> /dev/null
}

os="$(uname)"

if [ "$os" = 'Darwin' ]; then
  open -g "$video_url"
else
  if exists 'chrome'; then
    chrome "$video_url"
  elif exists 'google-chrome'; then
    google-chrome "$video_url"
  elif exists 'firefox'; then
    firefox "$video_url"
  elif exists 'iceweasel'; then
    iceweasel "$video_url"
  else
    echo "$video_url" > /home/*/look-at-this-$$.txt
