-.SH SYNOPSIS
-\fBtime [-C] \fIcommand\fR
-.br
-.de FL
-.TP
-\\fB\\$1\\fR
-\\$2
-..
-.de EX
-.TP 20
-\\fB\\$1\\fR
-# \\$2
-..
-The -C option tells time to report the cpu cycle counter
-difference.

-.TP 20
-.B time a.out
-# Report how long \fIa.out\fR takes

+.Sh NAME
+.Nm time
+.Nd time command execution
+.Sh SYNOPSIS
+.Nm
+.Op Fl clp
+.Ar command
+.Op Ar argument ...
+.Sh DESCRIPTION
+The
+.Nm
+utility
+executes and
+times
+.Ar command .
+After the command finishes,
+.Nm
+writes the total elapsed time (wall clock time),
+.Pq Dq real ,
+the CPU time spent executing
+.Ar command
+at user level
+.Pq Dq user ,
+and the CPU time spent executing in the operating system kernel
+.Pq Dq sys ,
+to the standard error stream.
+Times are reported in seconds.
+.Pp
+Available options:
+.Bl -tag -width Ds
+.It Fl c
+Displays information in the format used by the
+.Nm
+builtin of
+.Xr csh 1 .
+.It Fl l
+Lists resource utilization information.
+The contents of the
+.Ar command
+process's
+.Em rusage
+structure are printed; see below.
+.It Fl p
+The output is formatted as specified by
+.St -p1003.2-92 .
+.El
+.Pp
+Some shells, such as
+.Xr csh 1
+and
+.Xr ksh 1 ,
+have their own and syntactically different built-in version of
+.Nm .
+The utility described here
+is available as
+.Pa /usr/bin/time
+to users of these shells.
+.Ss Resource Utilization
+If the
+.Fl l
+option is given, the following resource usage
+information is displayed
+in addition to the timing information:
+.Bl -item -offset indent -compact
+.It
+maximum resident set size
+.It
+average shared memory size
+.It
+average unshared data size
+.It
+average unshared stack size
+.It
+page reclaims
+.It
+page faults
+.It
+swaps
+.It
+block input operations
+.It
+block output operations
+.It
+messages sent
+.It
+messages received
+.It
+signals received
+.It
+voluntary context switches
+.It
+involuntary context switches
+.El
+Resource usage is the total for the execution of
+.Ar command
+and any child processes it spawns, as per
+.Xr wait4 2 .
+.Sh FILES
+.Bl -tag -width Xsys/resource.hX -compact
+.It Aq sys/resource.h
+.El
+.Sh EXIT STATUS
+The
+.Nm
+utility exits with one of the following values:
+.Bl -tag -width indent
+.It 1-125
+An error occurred in the
+.Nm
+utility.
+.It 126
+The
+.Ar command
+was found but could not be invoked.
+.It 127
+The
+.Ar command
+could not be found.
+.El
+.Pp
+Otherwise, the exit status of
+.Nm
+will be that of
+.Ar command .
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr ksh 1 ,
+.Xr clock_gettime 2 ,
+.Xr getrusage 2
+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -p1003.2-92 .
+.Sh BUGS
+The granularity of seconds on microprocessors is crude and
+can result in times being reported for CPU usage which are too large by
+a second.
