Linux and Unix timex command
On Solaris, the timex command times a command and reports process data and system activity.
timex [-o] [-p [-f] [-h] [-k] [-m] [-r] [-t]] [-s] command
|-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:
|-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|
timex -ops sleep 60
sleep for 60 seconds, and reports how long the system actually "slept".
