Dinge, die man gerne immer wieder vergisst II

Heute: Sudo und Umleitungsoperatoren: Da es immer wieder gerne falsch gemacht wird:

sudo cat /irgendeine/datei > /etc/die_darf_nur_root_schreiben

Das sudo bezieht sich nur auf das cat nicht auf den Umleitungsoperator >! Korrekterweise muß es also lauten:

sudo sh -c 'cat /irgendeine/datei > /etc/die_darf_nur_root_schreiben'
