TIME(1) OpenBSD Reference Manual TIME(1)NAMEtime - time command execution
SYNOPSIStime [-lp] utility [argument ...]
DESCRIPTIONtime executes and times utility with optional arguments. 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.
The options are as follows:
-l The contents of the rusage structure are printed.
-p The output is formatted as specified by IEEE Std 1003.2-1992
(``POSIX.2'').
FILES
/usr/include/sys/resource.h
EXIT STATUS
The time utility exits 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 ALSOcsh(1), ksh(1), getrusage(2)STANDARDS
The time utility is compliant with the IEEE Std 1003.1-2008 (``POSIX'')
specification.
The flag [-l] is an extension to that specification.
time also exists as a built-in to csh(1) and ksh(1), though with a
different syntax.
HISTORY
A time command appeared in Version 3 AT&T UNIX.
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.
