verbessertes logging im linking workflow

[guenterh]

Aus dem Logging der aktuell genutzten Shellscripte ist häufig schlecht verständlich, wo und in welchem Kontext der Prozess sich befunden hat (und was die message damit genau bedeutet)

Mache die Messages aussagekräfiger und damit auch nachvollziehbarer für Dritte:

Beispiel für das aktuelle Logging:
