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).
−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 (500 by default). 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.
The exit status is 0 on success, nonzero on error.
