luseradd − Add an user

luseradd [OPTION]... user

Adds an user with name user.

−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 specified 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).

−r, −−reserved

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.
