w-Befehl für die anderen Netzwerkhosts

Während sich der whoBefehl auf die lokale Maschine bezieht, rwhozeigt er die gleichen Informationen überalledie bekannten Hosts des lokalen Netzwerks.

In ähnlicher Weise wwerden Informationen über die Benutzer auf dem lokalen Computer und ihre Prozesse angezeigt. Gibt es wein Äquivalent zu rwho, das dieselben Informationen, aber relativ zu allen anderen Hosts anzeigt?

Antwort1

Problemumgehung mitGNU parallel.

parallel --nonall --sshloginfile .cluster --tag w

In meinem Fall verwende ich eine Datei .cluster, die die Hostnamen enthält, auf denen ich den Befehl ausführen möchte:

$ cat .cluster
n04
n05
n06

Meine Ausgabe
