whodo Command

Purpose

Lists the jobs being performed by users on the system.

Syntax

whodo [ -h ] [ -l ] [ 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.

Flags

-h

Suppress the heading that is printed on the output.

-l

Produce a long form of output. A summary of the current activity on the system is printed. The summary includes the following:

User: Who is logged on.
tty: Name of the tty the user is on.
login@: Time of day the user logged on.
idle: Number of minutes since a program last attempted to read from the terminal.
JCPU: System unit time used by all processes and their children on that terminal.
PCPU: System unit time used by the currently active process.
what: Name and parameters of the current process.

The heading line of the summary shows the current time of day, how long the system has been up, the number of users logged into the system.

Parameters

User	Limits output to all sessions pertaining to the user specified with User. More than one user name cannot be specified at a time.

Exit Status

0: The command completed successfully.
>0: An error occurred.
