Dies ist kein Talk über ssh_config(5), vi, netrw, vimdiff, emacs, ssh-copy-id oder ClusterShell; aber er zeigt ausgewählte Beispiele die die vorgenannten Werkzeuge benutzen und die täglichen administrativen Aufgaben erheblich beschleunigen. Mit anderen Worten eine Einführung in fortgeschrittene administrative Techniken, im Sinne von: \"Moving Around in a Hurry\" aus dem Buch UNIX POWER TOOLS.\n\nAls Beispiel wird versucht folgende Aufgaben möglichst elegant zu lösen:\n * Aufgabe 1) Editieren und vergleichen zweier remote root Dateien (live)\n * Aufgabe 2) Beliebige Befehle auf 100+ nodes ausführen.
