`TrySystem()`

Versucht die Ausführung eines Shell-Befehls.

TrySystem(Befehl)

Führt wie System() einen Befehl auf der Shell sh aus, liefert aber stets 0 zurück, wohingegen System() bei einem Fehler -1 zurückgibt.

Setzt die Channelvariable SYSTEMSTATUS auf SUCCESS (erfolgreich ausgeführt), FAILURE (konnte nicht ausgeführt werden) oder APPERROR (Befehl ausgeführt aber mit Exit-Code ungleich 0).
