Use FILE instead of /etc/adduser.conf.
Do not run passwd to set the password. The user won't be able to use her account until the
password is set.
Like --disabled-login, but logins are still possible (for example using SSH RSA keys) but not
using password authentication.
By default, user and group names are checked against the configurable regular expression
NAME_REGEX (or NAME_REGEX_SYSTEM if --system is specified) specified in the configuration file.
This option forces adduser and addgroup to apply only a weak check for validity of the name.
Set the gecos field for the new entry generated. adduser will not ask for finger information if
this option is given.
When creating a group, this option forces the new groupid to be the given number. When creating a
user, this option will put the user in that group.
When combined with --system, a group with the same name and ID as the system user is created. If
not combined with --system, a group with the given name is created. This is the default action if
the program is invoked as addgroup.
--help Display brief instructions.
Use DIR as the user's home directory, rather than the default specified by the configuration file.
If the directory does not exist, it is created and skeleton files are copied.
Use SHELL as the user's login shell, rather than the default specified by the configuration file.
Add the new user to GROUP instead of a usergroup or the default group defined by USERS_GID in the
configuration file. This affects the users primary group. To add additional groups, see the
Do not create the home directory, even if it doesn't exist.
Suppress informational messages, only show warnings and errors.
Be verbose, most useful if you want to nail down a problem with adduser.
Create a system user or group.
Force the new userid to be the given number. adduser will fail if the userid is already taken.
Override the first uid in the range that the uid is chosen from (overrides FIRST_UID specified in
the configuration file).
Override the last uid in the range that the uid is chosen from ( LAST_UID )
Add new user to extra groups defined in the configuration file.
