OpenSolaris 2009.06 - man page for timex (opensolaris section 1)

timex(1)				  User Commands 				 timex(1)

       timex - time a command; report process data and system activity

       timex [-o] [-p [-fhkmrt]] [-s] command

       The given command is executed; the elapsed time, user time and system time spent in execu-
       tion are reported in seconds. Optionally, process accounting data for the command and  all
       its  children  can be listed or summarized, and total system activity during the execution
       interval can be reported.

       The output of timex is written on standard error.

       The following options are supported:

       -o    Report the total number of blocks read or written and total  characters  transferred
	     by   command  and all its children. This option works only if the process accounting
	     software is installed.

       -p    List process accounting records for command and all its children. This option  works
	     only if the process accounting software is installed. Suboptions  f, h, k, m, r, and
	     t modify the data items reported. The options are as follows:

	     -f    Print the fork(2)/ exec(2) flag and system exit status columns in the output.

	     -h    Instead of mean memory size, show the fraction of  total  available	CPU  time
		   consumed  by the process during its execution. This ``hog factor'' is computed
		   as (total CPU time)/(elapsed time).

	     -k    Instead of memory size, show total kcore-minutes.

	     -m    Show mean core size (the default).

	     -r    Show CPU factor (user time/(system-time + user-time)).

	     -t    Show separate system and user CPU times. The number of blocks read or  written
		   and the number of characters transferred are always reported.

       -s    Report  total  system  activity (not just that due to  command) that occurred during
	     the execution interval of	command.  All  the  data  items  listed  in   sar(1)  are

       Example 1 Examples of timex.

       A simple example:

	 example% timex -ops sleep 60

       A terminal session of arbitrary complexity can be measured by timing a sub-shell:

	 example% timex -opskmt sh
	       session commands

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWaccu			   |

       Process	 records   associated	with  command  are  selected  from  the  accounting  file
       /var/adm/pacct by inference, since process genealogy is	not  available.  Background  pro-
       cesses  having the same user ID, terminal ID, and execution time window will be spuriously
