Here is a program that you might find useful, people arround here have. It
parses the output from rwho and returns some interesting information.

rwhop is a program I wrote one bored Sunday night for something to do. I
was prompted to post this code for others to use. The main reason for the
program is to return the users real name instead of just the login name.
If there are any problems, send me mail and I will try to rectify the bug.

This coed is supplied without copyright, do with it what you please. (Tell
me of any improvements you have.) I was thinking of making the program
search for a host rather than just a user (maybe someday).

X.SH NAME
rwhop \- rwho(1) output parser
X.SH SYNTAX
X.B rwhop
X[
X.B \-ah
X] [\fIusers\fR]
X.SH DESCRIPTION
The
X.PN rwhop
command takes the output from rwho(1) via a pipe stream connection.
The returned information is the same as that of rwho with the following
exceptions: 1) fully qualified host names are truncated to the first level.
X2) The users' gecos information is retreived via the getpwnam(3) call.
The first field of the gecos information is printed un the heading of 'Real
Name'
X.SH OPTIONS
X.IP \fB\-a\fR 20
Lists all users. Normally,
X.PN rwhop
omits users who have not typed to the system for an hour or
more. If the
X.B \-a
flag is specified, these users are also listed.
X.IP \fB\-h\fR 20
Sorts users by host name. Normally,
X.PN rwhop
prints its output sorted by user name. If the
X.B \-h
flag is specified, the results are sorted by host name.
X.SH FILES
X/usr/spool/rwho/whod.* Information about other machines
