-w TARGETS,... Target and or filter the specified list of hosts.
-x host,host,... Exclude the specified hosts.
-S Return the largest of the remote command return values.
-k Fail fast on connect failure or non-zero return code.
-q List option values and the target nodelist and exit without action.

-t seconds Set the connect timeout. Default is 10 seconds.
-u seconds Set a limit on the amount of time a remote command is allowed to execute. Default is no limit.
