34.Sh DESCRIPTION
35The
36.Pa /etc/adduser.conf
37file is automatically generated by the
38.Xr adduser 8
39utility when invoked with the
40.Fl C
41command-line option.
42It is not meant to be edited by hand.
43.Pp
44The
45.Pa /etc/adduser.conf
46file is used to pre-set certain configuration options for
47the
48.Xr adduser 8
49utility.
50When
51.Xr adduser 8
52is invoked, it will check to see if this file exists, and
53if so, the configuration will be used or offered as the
54default settings.
55The
56.Nm
57file offers three types of configuration:
58.Bl -bullet
59.It
60Default settings offered by
61.Xr adduser 8 .
62These options are specified in the configuration file and offered
63as the default during every invocation of the
64.Xr adduser 8
65utility.
66.It
67Configuration options which can be set in

76.Pp
77In the first case, these options can be set in
78.Nm
79but will still be offered when
80.Xr adduser 8
81is invoked.
82In the second case,
83.Xr adduser 8
84will read the configuration data unless a flag
85has been passed to override it.
86For example, the
87.Va defaultshell
88option.
89In the third case, the configuration will be utilized, but the
90user will never be prompted to modify the default setting by
91either a flag or an
92.Xr adduser 8
93prompt.
94For example, the
95.Va upwexpire
96setting.
