Hallo,
ich würde mich da Adrian anschließen und alles als String lassen. Nur $#
als Integer vergleichen, denn da geht es ja tatsächlich um die Anzahl
der Parameter.
Wenn das ok ist mach ich den Patch dann so.
Bei den [ $do_reboot = "1" ] etc. wäre es ja eigentlich ein logischer
test. Also "is set" , die 1 hat da keine Bedeutung, das kann auch "ja"
sein. Das würde man dann z.B so machen:
[ ${do_reboot+x} ] && reboot Aber das versteht erstmal kaum einer ;-)
