user -- manage user login information on the system
SYNOPSIS
user add -D [options]
user add [options] user
user del -D [options]
user del [options] user
user info [options] user
user mod [options] user
DESCRIPTION
The user utility acts as a frontend to the useradd(8), usermod(8), userinfo(8), and userdel(8) commands. The utilities by default are built
with EXTENSIONS. This allows for further functionality.
For a full explanation of the options available, please see the relevant manual page.
EXIT STATUS
The user utility exits 0 on success, and >0 if an error occurs.
FILES
/etc/skel/.[A-z]* Skeleton files for new user
/etc/usermgmt.conf Configuration file for user, group(8) and the backend commands mentioned above.

The user utility first appeared in NetBSD 1.5. It is based on the addnerd package by the same author.

USERMOD(8) BSD System Manager's Manual USERMOD(8)NAME
usermod -- modify user login information
SYNOPSIS
usermod [-FmoSv] [-C yes/no] [-c comment] [-d home-dir] [-e expiry-time] [-f inactive-time] [-G secondary-group] [-g gid | name | =uid]
[-L login-class] [-l new-login] [-p password] [-s shell] [-u uid] user
DESCRIPTION
The usermod utility modifies user login information on the system.
Default values are taken from the information provided in the /etc/usermgmt.conf file, which, if running as root, is created using the built-
in defaults if it does not exist.
See user(8) for more information about EXTENSIONS.
After setting any defaults, and then reading values from /etc/usermgmt.conf, the following command line options are processed:
-C yes/no
Enable user accounts to be temporary locked/closed. The yes/no operand can be given as ``yes'' to lock the account or ``no'' to
unlock the account.
-c comment
Set the comment field (also, for historical reasons known as the GECOS field) for the user. The comment field will typically include
the user's full name and, perhaps, contact information for the user.
-d home-directory
Set the home directory without populating it; if the -m option is specified, tries to move the old home directory to home-directory.
-e expiry-time
Set the time at which the account expires. This can be used to implement password aging. It should be entered in the form ``month
day year'', where month is the month name (the first three characters are sufficient), day is the day of the month, and year is the
year. Time in seconds since the epoch (UTC) is also valid. A value of 0 can be used to disable this feature. This value can be
preset for all users using the expire field in the /etc/usermgmt.conf file. See usermgmt.conf(5) for more details.
-F Force the user to change their password upon next login.
-f inactive-time
Set the time at which the password expires. See the -e option.
-G secondary-group
Specify a secondary group to which the user will be added in the /etc/group file. The secondary-group may be a comma-delimited list
for multiple groups. Or the option may be repeated for multiple groups. (16 groups maximum.)
-g gid | name | =uid
Give the group name or identifier to be used for the user's primary group. If this is '=uid', then a uid and gid will be picked
which are both unique and the same, and a line will be added to /etc/group to describe the new group. This value can be preset for
all users by using the group field in the /etc/usermgmt.conf file. See usermgmt.conf(5) for more details.
-L login-class
Set the login class for the user. See login.conf(5) for more information on user login classes. This value can be preset for all
users by using the class field in the /etc/usermgmt.conf file. See usermgmt.conf(5) for more details. This option is included if
built with EXTENSIONS.
-l new-user
Give the new user name. It can consist of alphanumeric characters and the characters '.', '-', and '_'.
-m Move the home directory from its old position to the new one. If -d is not specified, the new-user argument of the -l option is
used; one of -d and -l is needed.
-o Allow duplicate uids to be given.
-p password
Specify an already-encrypted password for the user. This password can then be changed by using the chpass(1) utility. This value
can be preset for all users by using the password field in the /etc/usermgmt.conf file. See usermgmt.conf(5) for more details. This
option is included if built with EXTENSIONS.
-S Allow samba user names with a trailing dollar sign to be modified. This option is included if built with EXTENSIONS.
-s shell
Specify the login shell for the user. This value can be preset for all users by using the shell field in the /etc/usermgmt.conf
file. See usermgmt.conf(5) for more details.
-u uid Specify a new uid for the user. Boundaries for this value can be preset for all users by using the range field in the
/etc/usermgmt.conf file. See usermgmt.conf(5) for more details.
-v Enable verbose mode - explain the commands as they are executed. This option is included if built with EXTENSIONS.
Once the information has been verified, usermod uses pwd_mkdb(8) to update the user database. This is run in the background. At very large
sites this can take several minutes. Until this update is completed, the password file is unavailable for other updates and the new informa-
tion is not available to programs.
EXIT STATUS
The usermod utility exits 0 on success, and >0 if an error occurs.
