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
