The current time, how +long the system has been running, how many users are currently logged on, and +the system load averages for the past 1, 5, and 15 minutes. +.PP +This is the same information contained in the header line displayed by +.BR w (1). +.PP +System load averages is the average number of processes that are either in a +runnable or uninterruptable state. A process in a runnable state is either +using the CPU or waiting to use the CPU. A process in uninterruptable state +is waiting for some I/O access, eg waiting for disk. The averages are taken +over the three time intervals. Load averages are not normalized for the +number of CPUs in a system, so a load average of 1 means a single CPU system +is loaded all the time while on a 4 CPU system it means it was idle 75% of +the time. +.SH OPTIONS +.TP +\fB\-p\fR, \fB\-\-pretty\fR +show uptime in pretty format +.TP +\fB\-h\fR, \fB\-\-help\fR +display this help text +.TP +\fB\-s\fR, \fB\-\-since\fR +system up since, in yyyy-mm-dd HH:MM:SS format +.TP +\fB\-V\fR, \fB\-\-version\fR +display version information and exit +.SH FILES +.TP +.I /var/run/utmp +information about who is currently logged on +.TP +.I /proc +process information +.SH AUTHORS +.B uptime +was written by +.UR greenfie@gauss.\:rutgers.\:edu +Larry Greenfield +.UE +and +.UR johnsonm@sunsite.\:unc.\:edu +Michael K.
