time(1)                                                   time(1)



     NAME
          time - time a command

     SYNOPSIS
          time command

     DESCRIPTION
          time executes the command; afterward, 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 standard error output.

     EXAMPLE
               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
