Additional update on top of @ManuelReschke's version! I've added the eval command to support the usage of | and other more complex commands

watch() {
  local interval=1 # Standardintervall
  local command_to_run=""

  # Einfache Argumenten-Analyse
  if [[ "$1" == "-n" && "$2" =~ ^[0-9]+(\.[0-9]+)?$ ]]; then
    interval="$2"
    shift 2 # Entfernt -n und die Zahl von den Argumenten
  fi

  command_to_run="${@}"

  if [ -z "$command_to_run" ]; then
    echo "Usage: watch [-n <seconds>] <command>"
    return 1
  fi

  clear
  while true; do
    # Führe den Befehl aus und speichere Ausgabe und Fehler
    OUTPUT="$( eval "$command_to_run" 2>&1)"
    clear
    echo -e "Every ${interval}s: $command_to_run"
    echo ""
    echo -e "${OUTPUT}"
    sleep "$interval"
  done
}
