31 groupadd \- Crea un nuovo gruppo
33 .HP \w'\fBgroupadd\fR\ 'u
34 \fBgroupadd\fR [\fIopzioni\fR] \fIgroup\fR
39 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\&.
44 accetta le seguenti opzioni:
46 \fB\-f\fR, \fB\-\-force\fR
48 This option causes the command to simply exit with success status if the specified group already exists\&. When used with
49 \fB\-g\fR, and the specified GID already exists, another (unique) GID is chosen (i\&.e\&.
54 \fB\-g\fR, \fB\-\-gid\fR \fIGID\fR
56 Il valore numerico dell\*(Aqidentificatore (ID) del gruppo\&. Questo valore deve essere univoco, a meno che non venga usata l\*(Aqopzione
57 \fB\-o\fR\&. Il valore deve essere non\-negativo\&. La scelta predefinita \(`e quella di usare il minimo valore di ID superiore a 999 e superiore a qualunque altro gruppo\&. Valori tra 0 e 999 sono tipicamente riservati per account di sistema\&.
60 \fB\-h\fR, \fB\-\-help\fR
62 Mostra un messaggio di aiuto ed esce\&.
65 \fB\-K\fR, \fB\-\-key\fR \fIKEY\fR=\fIVALUE\fR
69 defaults (GID_MIN, GID_MAX and others)\&. Multiple
71 options can be specified\&.
74 \fB\-K \fR\fIGID_MIN\fR=\fI100\fR
75 \fB\-K \fR\fIGID_MAX\fR=\fI499\fR
79 \fIGID_MIN\fR=\fI10\fR,\fIGID_MAX\fR=\fI499\fR
80 doesn\*(Aqt work yet\&.
83 \fB\-o\fR, \fB\-\-non\-unique\fR
85 This option permits to add a group with a non\-unique GID\&.
88 \fB\-p\fR, \fB\-\-password\fR \fIPASSWORD\fR
90 The encrypted password, as returned by
91 \fBcrypt\fR(3)\&. The default is to disable the password\&.
95 This option is not recommended because the password (or encrypted password) will be visible by users listing the processes\&.
97 You should make sure the password respects the system\*(Aqs password policy\&.
100 \fB\-r\fR, \fB\-\-system\fR
102 Create a system group\&.
104 The numeric identifiers of new system groups are choosen in the
105 \fBSYS_GID_MIN\fR\-\fBSYS_GID_MAX\fR
107 login\&.defs, instead of
108 \fBGID_MIN\fR\-\fBGID_MAX\fR\&.
112 The following configuration variables in
114 change the behavior of this tool:
116 \fBGID_MAX\fR (number), \fBGID_MIN\fR (number)
118 Range of group IDs used for the creation of regular groups by
124 \fBMAX_MEMBERS_PER_GROUP\fR (number)
126 Maximum members per group entry\&. When the maximum is reached, a new group entry (line) is started in
128 (with the same name, same password, and same GID)\&.
130 The default value is 0, meaning that there are no limits in the number of members in a group\&.
132 This feature (split group) permits to limit the length of lines in the group file\&. This is useful to make sure that lines for NIS groups are not larger than 1024 characters\&.
134 If you need to enforce such limit, you can use 25\&.
136 Note: split groups may not be supported by all tools (even in the Shadow toolsuite)\&. You should not use this variable unless you really need it\&.
139 \fBSYS_GID_MAX\fR (number), \fBSYS_GID_MIN\fR (number)
141 Range of group IDs used for the creation of system groups by
150 Informazioni sugli account di gruppo\&.
155 Informazioni sicure sugli account di gruppo\&.
160 Shadow password suite configuration\&.
164 Groupnames must start 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_\-]*[$]?
166 Groupnames may only be up to characters long\&.
168 You may not add a NIS or LDAP group\&. This must be performed on the corresponding server\&.
170 If the groupname already exists in an external group database such as NIS or LDAP,
172 will deny the group creation request\&.
173 .SH "VALORI RESTITUITI"
177 command exits with the following values:

191 invalid argument to option
