TIME(1) MachTen Reference Manual TIME(1)

NAME
time - time command execution

SYNOPSIS
time [-l] command

DESCRIPTION
The time utility executes and times command by initiating a timer and
passing the command to the shell. After the command finishes, time
writes to the standard error stream, (in seconds): the total time
elapsed, time consumed by system overhead, and the time used to execute
the command process.

Available options:

-l The contents of the rusage structure are printed as well.

The csh(1) has its own and syntactically different builtin version of
time. The command described here is available as /usr/bin/time to csh
users.

BUGS
The granularity of seconds on micro processors is crude and can result in
times being reported for CPU usage which are too large by a second.
