whodo Command

Purpose

Lists the jobs being performed by users on the system.

Syntax

whodo [ -h ] [ -l ] [ -X ] [ User ]

Description

Prints information on all processes for a terminal, as well as the child processes.

By default, the output generated by the command for each active logged user will contain name of the terminal, user ID, date login time. The output is headed by the date, time and machine name. This information is followed by a record of active processes associated with that user ID. Each record shows the terminal name, process-ID, CPU minutes and seconds used, and process name.
