TIME(1)                 COMMAND REFERENCE                 TIME(1)



NAME
     time - time a command

SYNOPSIS
     time command

DESCRIPTION
     The given command is executed; after it is complete, time
     prints the elapsed time during the command, the time spent
     in the system, and the time spent in execution of the
     command.  Times are reported in seconds.

     The times are printed on the diagnostic output stream
     (standard error).

     The signals interrupt, quit, and terminate are ignored.

EXAMPLES
     The following example runs the command ls(1) with some
     options and prints the amount of time it took to run the
     command:

          time ls -al

RETURN VALUE
     The exit status returned is that of the command being timed.
     If the command does not exist, the exit status is NP_ERR.

     [NO_ERRS]      Command completed without error.

     [USAGE]        Incorrect command line syntax. Execution
                    terminated.

     [NP_ERR]       An error occurred that was not a system
                    error.  Execution terminated.

     [P_ERR]        A system error occurred. Execution
                    terminated.  See intro(2) for more
                    information on system errors.

CAVEATS
     Elapsed time is accurate to the second, while the CPU times
     are measured to the 60th second.  Thus, the sum of the CPU
     times can be up to a second larger than the elapsed time.
