ADDUSER.CONF(5) BSD File Formats Manual ADDUSER.CONF(5)NAMEadduser.conf — adduser(8) configuration file
The /etc/adduser.conf file is automatically generated by the adduser(8)
utility when invoked with the -C command-line option. It is not meant to
be edited by hand.
The /etc/adduser.conf file is used to pre-set certain configuration
options for the adduser(8) utility. When adduser(8) is invoked, it will
check to see if this file exists, and if so, the configuration will be
used or offered as the default settings. The adduser.conf file offers
three types of configuration:
· Default settings offered by adduser(8). These options are specified
in the configuration file and offered as the default during every
invocation of the adduser(8) utility.
· Configuration options which can be set in adduser.conf, but overrid‐
den by passing a flag to adduser(8).
· Configuration supported by adduser(8) but not offered by a flag or
during initial invocation.
In the first case, these options can be set in adduser.conf but will
still be offered when adduser(8) is invoked. In the second case,
adduser(8) will read the configuration data unless a flag has been passed
to override it. For example, the defaultshell option. In the third
case, the configuration will be utilized, but the user will never be
prompted to modify the default setting by either a flag or an adduser(8)
prompt. For example, the upwexpire setting.
The following configuration options can be set in adduser.conf:
defaultLgroup The default group new users will be added to.
defaultclass The default class to place users in as described in
defaultgroups This option is used to specify what other groups the
new account should be added to.
passwdtype May be one of no, none, random, or yes, as described
in adduser(8). As such, the text is not duplicated
here and may be read in adduser(8).
homeprefix The default home directory prefix, usually /home.
defaultshell The user's default shell which may be any of the
shells listed in shells(5).
udotdir Defines the location of the default shell and envi‐
ronment configuration files.
msgfile Location of the default new user message file. This
message will be sent to all new users if specified
here or at the adduser(8) prompt.
disableflag The default message enclosed in brackets for the
lock account prompt.
upwexpire The default password expiration time. Format of the
date is either a UNIX time in decimal, or a date in
dd-mmm-yy[yy] format, where dd is the day, mmm is
the month in either numeric or alphabetic format,
and yy[yy] is either a two or four digit year. This
option also accepts a relative date in the form of
n[mhdwoy] where n is a decimal, octal (leading 0) or
hexadecimal (leading 0x) digit followed by the num‐
ber of Minutes, Hours, Days, Weeks, Months or Years
from the current date at which the expiration time
is to be set.
uexpire The default account expire time. The format is sim‐
ilar to the upwexpire option.
ugecos The default information to be held in the GECOS
field of /etc/master.passwd.
uidstart The default user ID setting. This must be a number
above 1000 and fewer than 65534.
