WHODO(8) Maintenance Commands and Procedures WHODO(8)

NAME

whodo - who is doing what

SYNOPSIS

/usr/sbin/whodo [-h] [-l] [user]

DESCRIPTION

The whodo command produces formatted and dated output from
information in the /var/adm/utmpx and /proc/pid files.


The display is headed by the date, time, and machine name. For each
user logged in, device name, user-ID and login time is shown,
followed by a list of active processes associated with the user-ID.
The list includes the device name, process-ID, CPU minutes and
seconds used, and process name.


If user is specified, output is restricted to all sessions pertaining
to that user.

OPTIONS

The following options are supported:

-h
Suppress the heading.


-l
Produce a long form of output. The fields displayed are: the
user's login name, the name of the tty the user is on, the time
of day the user logged in (in ISO time format, weekday name and
hours:minutes, or ISO date format), the idle time -- that is,
the time since the user last typed anything (in
hours:minutes:seconds), the CPU time used by all processes and
their children on that terminal (in hours:minutes:seconds), the
CPU time used by the currently active processes (in
hours:minutes:seconds), and the name and arguments of the
current process.

ENVIRONMENT VARIABLES

If any of the LC_* variables (LC_CTYPE, LC_MESSAGES, LC_TIME,
LC_COLLATE, LC_NUMERIC, and LC_MONETARY) (see environ(7)) are not set
in the environment, the operational behavior of tar(1) for each
corresponding locale category is determined by the value of the LANG
environment variable. If LC_ALL is set, its contents are used to
override both the LANG and the other LC_* variables. If none of the
above variables is set in the environment, the "C" (U.S. style)
locale determines how whodo behaves.

LC_CTYPE
Determines how whodo handles characters. When LC_CTYPE
is set to a valid value, whodo can display and handle
text and filenames containing valid characters for
that locale. The whodo command can display and handle
Extended Unix code (EUC) characters where any
individual character can be 1, 2, or 3 bytes wide.
whodo can also handle EUC characters of 1, 2, or more
column widths. In the "C" locale, only characters from
ISO 8859-1 are valid.


LC_MESSAGES
Determines how diagnostic and informative messages are
presented. This includes the language and style of the
messages, and the correct form of affirmative and
negative responses. In the "C" locale, the messages
are presented in the default form found in the program
itself (in most cases, U.S. English).


LC_TIME
Determines how whodo handles date and time formats. In
the "C" locale, date and time handling follow the U.S.
rules.

EXIT STATUS

The following exit values are returned:

0
Successful completion.


non-zero
An error occurred.

FILES

/etc/passwd
System password file


/var/adm/utmpx
User access and administration information


/proc/pid
Contains PID
