About timex

On Solaris, the timex command times a command and reports process data and system activity.

timex syntax

timex [-o] [-p [-f] [-h] [-k] [-m] [-r] [-t]] [-s] command

Options

-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. Sub options f, h, k, m, r, and t modify the data items reported. The options are as follows:

-f Print the fork/exec 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 are reported.
command Name of the command to execute
