TIME(1)			  BSD General Commands Manual		       TIME(1)

NAME
     timetime 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.

SEE ALSO
     csh(1)

FILES
     /usr/include/sys/h/resource.h

HISTORY
     A time command appeared in Version 6 AT&T UNIX.
