time(1)                                                   time(1)



NAME
     time - prints the elapsed time during  the  execution  of  a
     command

SYNOPSIS
     time command

ARGUMENTS
     command
          Specifies the user-specified command that is being
          timed.

DESCRIPTION
     time executes the command then 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 standard error output.

EXAMPLES
     The command:

        time nroff -mm filea

     will, in sh, perform the formatting and report the time at
     the end of the file, e.g.:

        real  22.0
        user   8.6
        sys    6.4

     In csh, where time is a built-in command, the time report
     might be:

        8.9u  7.0s  0:29  54%

     which reports, respectively, the user time, system time,
     real time, and percentage of real time that the CPU was
     active, which is the sum of the user and system times
     divided by the real elapsed time.

FILES
     /bin/time
          Executable file
