NAME
luseradd - Add an user
SYNOPSIS
luseradd [OPTION]... user
DESCRIPTION
Adds an user with name user.
OPTIONS
-c, --gecos=gecos
Set the GECOS field to gecos. The GECOS field is traditionally used to store user's real name and other information.
-d, --directory=directory
Set user's home directory to directory. If this option is not present, a default specified by libuser configuration is used.
-g, --gid=group
Set user's primary group to group. group can either be a group ID of an existing group, or a group name; if group is a group name
and the group does not exist, it is created. If the --gid option is not specified, the default group name is user.
-i, --interactive
Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration.
-k, --skeleton=directory
Populate the newly created user's home directory with a copy of directory. If this option is not present, a default directory spec-
ified by libuser configuration, or /etc/skel if libuser configuration does not specify a default, is used.
-M, --nocreatehome
Don't create a home directory and a mail spool for the newly created user.
-n, --nocreategroup
If a group is not specified using -g, use group name "users" instead of user. Note that despite the name of the option, the group
will still be created if it does not exist.
-P, --plainpassword=password
Set user's password to password. Note that the password can be viewed while running luseradd using tools such as ps(1).
-p, --password=encrypted
Set user's password to the password represented by the hash encrypted. Note that the hash can be viewed while running luseradd
using tools such as ps(1).
-r, --reserved
The user is a system user. Users that are not marked as system user usually have automatically selected user IDs above a certain
value (configured as LU_UIDNUMBER in libuser.conf(5)). This information is also passed to the libuser backends. This option
implies the -M option.
-s, --shell=shell
Set user's login shell to shell. If this option is not present, a default specified by libuser configuration is used.
-u, --uid=uid
Use user ID uid for the newly created user. An user ID is selected automatically if this option is not present.
--commonname=name

have further limitations (e.g. LDAP schema rules).

have further limitations (e.g. LDAP schema rules).
--homephone=phone

support may have further limitations (e.g. LDAP schema rules).
--roomnumber=room

have further limitations (e.g. LDAP schema rules).
