Schicke mir https://t.me/'"${ME//_/\\_}"' einen Befehl mit *max. 50 Begriffen*. Ein Begriff muss mindesten 4 Zeichen lang sein.

*Befehle zum Suchen / Tracken  von Dealz:*
  /search  /suche _Suche in Deals der letzen 48h,
  z.B.:_ /suche   Apple  mavic.\*air

  /newtrack   _Tracking mit neuen Begriffen,
  z.B.:_ /newtrack    Apple  mavic.\*air
  /track /addkey   _zusätzlicher Begriff zum Tracken_
  /delkey       _lösche Begriff_

  /listtrack   _zeigt aktuell getrackte Begriffe_
  /delkey ALL  _löscht alle Begriffe_ 
  /stattrack   _Infos zum aktiven Tracking_

'

bashbot_commands='*Meine Befehle*:
  /info      _- Info zum Bot_
  /suche     _- Suchen und Tracken von Dealz_
  /hilfe    _- Hilfe zu weiteren Befehlen_
