The utility

+Removes the user's
.Xr crontab 1
-entry (if any) and any
+entry (if any).
+.It
+Removes any
.Xr at 1
-jobs belonging to the user,
-then removes a user from the system's local password file, removes
-the user's home directory if it is owned by the user, and removes
-the user's incoming mail file if it exists. The username is removed
-from any groups to which it belongs in the file
+jobs belonging to the user.
+.It
+Sends a SIGKILL signal to all processes owned by the user.
+.It
+Removes the user from the system's local password file.
+.It
+Removes the user's home directory (if it is owned by the user),
+including handling of symbolic links in the path to the actual home
+directory.
+.It
+Removes the incoming mail and pop daemon mail files belonging to the
+user from
+.Pa /var/mail .
+.It
+Removes all files owned by the user from
+.Pa /tmp ,
+.Pa /var/tmp ,
+and

+.El
.Pp
-.Nm rmuser
+.Nm Rmuser
politely refuses to remove users whose uid is 0 (typically root), since
-it seemed like a good idea at the time
-.Nm rmuser
-was written.
+certain actions (namely, killing all the user's processes, and perhaps
+removing the user's home directory) would cause damage to a running system.
+If it is necessary to remove a user whose uid is 0, see
+.Xr vipw 8
+for information on directly editing the password file, by which the desired
+user's
+.Xr passwd 5
+entry may be removed manually.
.Pp
-.Nm rmuser
+If not running "affirmatively" (i.e., option
+.Fl y
+is not specified),
+.Nm
shows the selected user's password file entry and asks for confirmation
that you wish to remove the user. If the user's home directory is owned
-by the user (and not by any other user),
-.Nm rmuser
+by the user,
+.Nm
asks whether you wish to remove the user's home directory and everything
below.
.Pp
+As
+.Nm
+operates, it informs the user regarding the current activity. If any
+errors occur, they are posted to standard error and, if it is possible for
+.Nm
+to continue, it will.
+.Pp
Available options:
.Pp
.Bl -tag -width username
+.It Fl y
+Affirm - any question that would be asked is answered implicitly in
+the affirmative (i.e., yes). A username must also be specified on the
+command line if this option is used.
.It Ar \&username
Identifies the user to be removed; if not present,
-.Nm rmuser
+.Nm
interactively asks for the user to be removed.

+.Sh BUGS
+.Nm Rmuser
+does not comprehensively search the filesystem for all files
+owned by the removed user and remove them; to do so on a system
+of any size is prohibitively slow and I/O intensive.
+.Nm Rmuser
+also is unable to remove symbolic links that were created by the
+user in
+.Pa /tmp
+or
+.Pa /var/tmp
+as symbolic links on 4.4BSD filesystems do not contain information
+as to who created them. Also, there may be other files created in
+.Pa /var/mail
+other than
+.Pa /var/mail/username
+and
+.Pa /var/mail/.pop.username
+that are not owned by the removed user but should be removed.
+.Pp
+.Nm Rmuser
+has no knowledge of NIS (Yellow Pages), and it operates only on the
+local password file.
