time

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

NAME

     time -- time command execution

SYNOPSIS

     time [-lp] utility

DESCRIPTION

     The time utility executes and times utility.  After the utility finishes, time writes the total time elapsed, the time consumed by system
     overhead, and the time used to execute utility to the standard error stream.  Times are reported in seconds.

     Available options:

     -l      The contents of the rusage structure are printed.

     -p      The output is formatted as specified by IEEE Std 1003.2-1992 (``POSIX.2'').

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

DIAGNOSTICS

     The time utility shall exit with one of the following values:

     1-125   An error occurred in the time utility.

     126     The utility was found but could not be invoked.

     127     The utility could not be found.

     Otherwise, the exit status of time shall be that of utility.

SEE ALSO

     csh(1), getrusage(2)

FILES

     /usr/include/sys/resource.h

STANDARDS

     The time utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').

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.
