timex(1)                         User Commands                        timex(1)



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

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

DESCRIPTION
       The  given  command is executed; the elapsed time, user time and system
       time spent in execution 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.

OPTIONS
       The following options are supported:

       -o    Report the total number of blocks read or written and total char‐
             acters 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 col‐
                   umns in the output.


             -h    Instead  of  mean  memory  size, show the fraction of total
                   available CPU time consumed by the process during its  exe‐
                   cution.  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 trans‐
                   ferred 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 reported.


EXAMPLES
       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
         EOT

NOTES
       Process records associated with command are selected from the  account‐
       ing  file  /var/adm/pacct  by inference, since process genealogy is not
       available. Background processes having the same user ID,  terminal  ID,
       and execution time window will be spuriously included.
