or all hosts on the local network. The output shows the current time of day, how long the system has been up, and the load averages. The load average numbers give the number of jobs in the run queue averaged over 1, 5 and 15 minutes.
The following options are available:
For each host, report what it's local time is. This is useful for checking time synchronization on a network.
Sort the display alphabetically by host name.
Sort the display by load average.
Sort the display by up time.
