      TIME(1)                 GENIX Programmer's Manual                 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.

           On a PDP-11, the execution time can depend on what  kind  of  memory
           the  program  happens to land in; the user time in MOS is often half
           what it is in core.

           The times are printed on the diagnostic output stream.

           Time is built in to csh(1), using a different output format.

      BUGS
           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.

           Time is a built-in command to csh(1), with a much different  syntax.
           This command is available as ``/bin/time'' to csh users.
