With specified flags, the timex command lists or summarizes process accounting data for a command and all of its children. Command is the name of any executable file on the system. It also reports total system activity during the execution interval. Output is written to standard error. The system uses the /var/adm/pacct file to select process records associated with the command and includes background processes with the same user ID, workstation ID, and execution time window.
