lnewusers - Create new user accounts


lnewusers [OPTION]...


Creates new user accounts using data read from standard input.

The input data consists of lines, each line has 7 colon-separated fields:

lnewusers refuses to create users with user ID 0 (the root user ID).

If this field is a valid group ID, it is interpreted as a group ID, otherwise as a group name. If the field is empty, a group name equal to user name is used.

If the specified group does not exist, it is automatically created. If the group is specified with a group ID, the created group has group name equal to the user name.

The GECOS field is traditionally used to store user's real name and other information.

If this field is empty, a default specified by libuser configuration, or /home/username if libuser configuration does not specify a default, is used.

If this field is empty, a default specified by libuser configuration is used.

Errors in user specifications are reported and processing continues on the next line.


Read account data from file instead of standard input.

Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration.

Don't create home directories.

Don't create mail spool files.


The exit status is 0 on success, nonzero on fatal error. Errors in user specifications are not reflected in the exit status.
