TIME(1)			     BSD Reference Manual		       TIME(1)

NAME
     time - time command execution

SYNOPSIS
     time [-l] command [arg ...]

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.

     The options are as follows:

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

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

     The time utility exits 127 if unable to execute the command, 126 if the
     command did not exit, and otherwise the command's exit value.

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),  getrusage(2)

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