lnewusers

lnewusers(1)						      General Commands Manual						      lnewusers(1)

NAME

       lnewusers - Create new user accounts

SYNOPSIS

       lnewusers [OPTION]...

DESCRIPTION

       Creates new user accounts using data read from standard input.

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

       User name

       Plaintext password

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

       Group  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.

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

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

       Login shell
	      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.

OPTIONS

       -f, --file=file
	      Read account data from file instead of standard input.

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

       -M, --nocreatehome
	      Don't create home directories.

       -n, --nocreatemail
	      Don't create mail spool files.

EXIT STATUS

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