Synopsis
luseradd [OPTION]… userDescription
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 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.
