Home directory. The default is to use user as the directory name under the home directory specified with the -D option.

-e date

Account expiration date. Use the format MM/DD/YYYY. Two-digit year fields are also accepted. The value is stored as the number of days since January 1, 1970. This option requires the use of shadow passwords.

-f days

Permanently disable account this many days after the password has expired. A value of -1 disables this feature. This option requires the use of shadow passwords.

Initial group name or ID number. If a different default group has not been specified using the -D option, the default group is 1.

-G groups

Supplementary groups given by name or number in a comma-separated list with no whitespace.

Copy default files to the user's home directory. Meaningful only when used with the -m option. Default files are copied from /etc/skel/ unless an alternate dir is specified.

Make user's home directory if it does not exist. The default is not to make the home directory.

-M

Do not create a home directory for the user, even if the system default in /etc/login.defs is to create one.

-n

Red Hat-specific option. Turn off the Red Hat default that creates a group with the same name as the username and puts the user in that group.

Override. Accept a nonunique uid with the -u option. (Probably a bad idea.)

-p passwd

The encrypted password, as returned by crypt(3).

Expire date. Requires the use of shadow passwords.
