30.Dt RMUSER 8
31.Os
32.Sh NAME
33.Nm rmuser
34.Nd removes users from the system
35.Sh SYNOPSIS
36.Nm
37.Op Fl y
38.Op Ar username
39.Sh DESCRIPTION
40The
41.Nm
42utility
43.Pp
44.Bl -enum
45.It
46Removes the user's
47.Xr crontab 1
48entry (if any).
49.It
50Removes any
51.Xr at 1
52jobs belonging to the user.
53.It
54Sends a SIGKILL signal to all processes owned by the user.
55.It
56Removes the user from the system's local password file.
57.It
58Removes the user's home directory (if it is owned by the user),
59including handling of symbolic links in the path to the actual home
60directory.
61.It
62Removes the incoming mail and pop daemon mail files belonging to the
63user from
64.Pa /var/mail .
65.It
66Removes all files owned by the user from
67.Pa /tmp ,
68.Pa /var/tmp ,
69and
70.Pa /var/tmp/vi.recover .
71.It
72Removes the username from all groups to which it belongs in
73.Pa /etc/group .
74(If a group becomes empty and the group name is the same as the username,
75the group is removed; this complements
76.Xr adduser 8 Ns 's
77per-user unique groups).
78.El
79.Pp
80The
81.Nm
82utility
83politely refuses to remove users whose uid is 0 (typically root), since
84certain actions (namely, killing all the user's processes, and perhaps
85removing the user's home directory) would cause damage to a running system.
86If it is necessary to remove a user whose uid is 0, see
87.Xr vipw 8
88for information on directly editing the password file, by which the desired
89user's
90.Xr passwd 5
91entry may be removed manually.
92.Pp
93If not running "affirmatively" (i.e., option
94.Fl y
95is not specified),
96.Nm
97shows the selected user's password file entry and asks for confirmation
98that you wish to remove the user.  If the user's home directory is owned
99by the user,
100.Nm
101asks whether you wish to remove the user's home directory and everything
102below.
103.Pp
104As
105.Nm
106operates, it informs the user regarding the current activity.  If any
107errors occur, they are posted to standard error and, if it is possible for
108.Nm
109to continue, it will.
110.Pp
111Available options:
112.Pp
113.Bl -tag -width username
114.It Fl y
115Affirm - any question that would be asked is answered implicitly in
116the affirmative (i.e., yes).  A username must also be specified on the
117command line if this option is used.
118.It Ar \&username
119Identifies the user to be removed; if not present,
120.Nm
121interactively asks for the user to be removed.

142.Sh HISTORY

145utility appeared in

149.Sh BUGS
150The
151.Nm
152utility does not comprehensively search the filesystem for all files
153owned by the removed user and remove them; to do so on a system
154of any size is prohibitively slow and I/O intensive.
155The
156.Nm
157utility also is unable to remove symbolic links that were created by the
158user in
159.Pa /tmp
160or
161.Pa /var/tmp
162as symbolic links on
163.Bx 4.4
164filesystems do not contain information
165as to who created them.  Also, there may be other files created in
166.Pa /var/mail
167other than
168.Pa /var/mail/username
169and
170.Pa /var/mail/.pop.username
171that are not owned by the removed user but should be removed.
172.Pp
173The
174.Nm
175utility has no knowledge of NIS (Yellow Pages), and it operates only on the
176local password file.
