TIMEX(1) — Silicon Graphics
NAME
timex − time a command; report process data and system activity
SYNOPSIS
timex [options] 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 are:
−p List process accounting records for command and all its children. Suboptions f, h, k, m, r, and t modify the data items reported, as defined in acctcom(1). The number of blocks read or written and the number of characters transferred are always reported.
−o Report the total number of blocks read or written and total characters transferred by command and all its children.
−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.
SEE ALSO
WARNING
Process records associated with command are selected from the accounting file /usr/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.
EXAMPLES
A simple example:
timex −ops sleep 60
A terminal session of arbitrary complexity can be measured by timing a sub-shell:
timex −opskmt sh
session commands
