Nein, macht es nicht:
- job 1 wird im Background ausgeführt
- job 2 wird im Background ausgeführt
- job 3 wird im Vordergrund ausgeführt
nach *erfolgreichem* beenden von job 3 wird job 4 ausgeführt.

Die Klammern um job 1 bis job 3 sorgen nur dafür, dass das Environment
(bis auf den Rückgabewert) nicht verändert wird.

(sleep 60 & sleep 60 & sleep 5) && echo "Fertig!"
