.SH NAME
top \- show processes sorted by CPU usage
.SH SYNOPSIS
.B top
\fBtop\fP [\fB\-s\fIdelay\fP] [\fB\-B\fP]
.SH DESCRIPTION
Top displays a list of all running processes, once every update interval
(currently 5 seconds). It is sorted by the CPU usage of the processes in
the last interval. The first display is the CPU usage of processes since
the boot time.
.SH OPTIONS
.PP
\fB\-s\fP\fIdelay\fP The number of seconds between screen updates.
\fB\-B\fP Blocked-verbose mode.
For every process that is blocked,
display the chain of block-dependencies up until the process
that is either not blocked or blocked on ANY.
At the top of the screen, top shows the current system load averages in
the last 1-minute, 5-minute and 15-minute intervals. Then, over the
last top interval it displays: the number of alive, active, and sleeping
processes; memory free; and CPU usage. CPU usage is split into
user, kernel, system and idle time. Kernel time is time spent by kernel tasks,
that is tasks that run in kernel mode in kernel address space. System
time are system user processes, such as drivers and servers. User
time is all other CPU time.
user, kernel, system and idle time. Kernel time is time spent in
the kernel. System time are system user processes, such as drivers and

Then it displays all the alive processes sorted by CPU usage in the last
interval, with a number of fields for every process. Currently the
