TIME(I)                      8/16/73                      TIME(I)


     time - time a command


     time command


     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


     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.


     Notice that time x >y puts the timing  information  into  y.

     One can get around this by time sh followed by x >y.

     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.
