  powershell.exe -NoProfile -C "if (Get-Module -ListAvailable -Name BurntToast) { toast -t \"$*\" } else { echo 'Please run \`Install-Module -Name BurntToast\` in a Powershell as administrator'; echo \"$*\" }"
}
toast_title_body() {
  toast $1\", \"$2
}

longrunning() {
  start=`date +%s`
  $*
  end=`date +%s`
  runtime=$((end-start))
  if [ $runtime -gt 5 ]; then
    toast_title_body "command finished (${runtime}s)" "$*"
  fi
}
