   Hallo Freunde,
   
   ich bin gerade dabei mich mit curl und de REST API von vCloud vertraut zu machen.
   Das Skript habe ich als Bash Script angefangen.
   Ziel ist es, per curl command die notwendigen Informationen (org, vapp, etc.) abzuholen um dann letztendlich eine vm per Skript in einer existierenden "leeren" vApp anzulegen.
   
   Hat hierbei jemand bereits Erfahrungen sammeln können? Gibt es vielleicht andere nützliche Alternativen, die das Handling deutlich erleichtern?

   function logsetup {
       TMP=$(tail -n $RETAIN_NUM_LINES $LOGFILE 2>/dev/null) && echo "${TMP}" > $LOGFILE
       exec > >(tee -a $LOGFILE)
       exec 2>&1
   }
   
   function log {
       echo "[$(date)]: $*"
