TIME(1)         DOMAIN/IX Reference Manual (SYS5)         TIME(1)



NAME
     time - time a command

USAGE
     time command

DESCRIPTION
     Time prints the amount of time it took for you to input the
     command, as well as the amount of time it took to execute
     it.  Times are reported in seconds, and are printed on stan-
     dard error.

EXAMPLE
     Time is helpful in reporting the CPU usage of a program.
     The information is printed on standard error, so commands
     that typically generate large quantities of output can be
     timed by sending the standard output to /dev/null, as in the
     following example:

           $ time grep e /usr/bin/words > dev/null

           real      7.5
           user      2.9

     The numbers in the output of time are elapsed clock (real)
     time and time spent in the program (user).

RELATED INFORMATION
     times (2).
