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