Oliver Voelker 7778ce70ed diverse Aenderungen an Shell-Scripten
- Klammern um if-Statements
  - == als Vergleichsoperator gibts nur in der Bash, wir haben aber nur sh (ash) verfuegbar

es ist nicht auszuschliessen, dass die Aenderungen nun andere Fehler zur Folge haben, wo vorher keine waren, da das Script doch irgendwie die "richtigen" Werte hatte.
Die bourne shell (sh) ist nicht so umfangreich wie die bourne again shell (bash).
