NAZWA¶
groupadd - utwórz nową grupę
STRESZCZENIE¶
groupadd [opcje] group
OPIS¶
The groupadd command creates a new group account using the values specified on the command line plus the default values from the system. The new group will be entered into the system files as needed.
OPCJE¶
The options which apply to the groupadd command are:
-f, --force
-g, --gid GID
See also the -r option and the GID_MAX description.
-h, --help
-K, --key KEY=VALUE
Example: -K GID_MIN=100 -K GID_MAX=499
Note: -K GID_MIN=10,GID_MAX=499 doesn't work yet.
-o, --non-unique
-p, --password PASSWORD
Note: This option is not recommended because the password (or encrypted password) will be visible by users listing the processes.
You should make sure the password respects the system's password policy.
-r, --system
The numeric identifiers of new system groups are chosen in the SYS_GID_MIN-SYS_GID_MAX range, defined in login.defs, instead of GID_MIN-GID_MAX.
-R, --root CHROOT_DIR
-P, --prefix PREFIX_DIR
-U, --users
The default behavior (if the -g, -N, and -U options are not specified) is defined by the USERGROUPS_ENAB variable in /etc/login.defs.
CONFIGURATION¶
The following configuration variables in /etc/login.defs change the behavior of this tool:
PLIKI¶
/etc/group
/etc/gshadow
/etc/login.defs
OSTRZEŻENIA¶
It is usually recommended to only use groupnames that begin with a lower case letter or an underscore, followed by lower case letters, digits, underscores, or dashes. They can end with a dollar sign. In regular expression terms: [a-z_][a-z0-9_-]*[$]?
On Debian, the only constraints are that groupnames must neither start with a dash ('-') nor plus ('+') nor tilde ('~') nor contain a colon (':'), a comma (','), or a whitespace (space:' ', end of line: '\n', tabulation: '\t', etc.).
Groupnames may only be up to 32 characters long.
You may not add a NIS or LDAP group. This must be performed on the corresponding server.
If the groupname already exists in an external group database such as NIS or LDAP, groupadd will deny the group creation request.
