\fB/usr/sbin/whodo\fR [\fB-h\fR] [\fB-l\fR] [\fIuser\fR]

.SH DESCRIPTION
.sp
.LP
The \fBwhodo\fR command produces formatted and dated output from information in
the \fB/var/adm/utmpx\fR and \fB/proc/pid\fR files.
.sp
.LP
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.
.sp
.LP
If \fIuser\fR is specified, output is restricted to all sessions pertaining to
that user.
.SH OPTIONS

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
\fIhours\fR\fB:\fR\fIminutes\fR), the idle time \(em that is, the time since
the user last typed anything (in \fIhours\fR\fB:\fR\fIminutes\fR), the CPU time
used by all processes and their children on that terminal (in
\fIminutes\fR\fB:\fR\fIseconds\fR), the CPU time used by the currently active
processes (in \fIminutes\fR\fB:\fR\fIseconds\fR), and the name and arguments of
the current process.

.SH ENVIRONMENT VARIABLES
.sp
.LP
If any of the \fBLC_*\fR variables ( \fB\fR\fBLC_CTYPE\fR\fB,\fR
\fBLC_MESSAGES\fR\fB,\fR \fBLC_TIME\fR\fB,\fR \fBLC_COLLATE\fR\fB,\fR
\fBLC_NUMERIC\fR\fB,\fR and \fBLC_MONETARY\fR ) (see \fBenviron\fR(5)) are not
set in the environment, the operational behavior of \fBtar\fR(1) for each
corresponding locale category is determined by the value of the \fBLANG\fR
environment variable. If \fBLC_ALL\fR is set, its contents are used to override
both the \fBLANG\fR and the other \fBLC_*\fR variables. If none of the above
variables is set in the environment, the "C" (U.S. style) locale determines how
\fBwhodo\fR behaves.
.sp
.ne 2
.mk
.na
\fB\fBLC_CTYPE\fR\fR
.ad
.RS 15n
.rt  
Determines how \fBwhodo\fR handles characters. When \fBLC_CTYPE\fR is set to a
valid value, \fBwhodo\fR can display and handle text and filenames containing
valid characters for that locale. The \fBwhodo\fR command can display and
handle Extended Unix code (EUC) characters where any individual character can
be 1, 2, or 3 bytes wide. \fBwhodo\fR can also handle EUC characters of 1, 2,
or more column widths. In the "C" locale, only characters from ISO 8859-1 are
valid.
.RE

.sp
.ne 2
.mk
.na
\fB\fBLC_MESSAGES\fR\fR
.ad
.RS 15n
.rt  
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).
.RE

.sp
.ne 2
.mk
.na
\fB\fBLC_TIME\fR\fR
.ad
.RS 15n
.rt  
Determines how \fBwhodo\fR handles date and time formats. In the "C" locale,
date and time handling follow the U.S. rules.
