Use only with the \fB\-G\fR option\&. .RE .PP \fB\-c\fR, \fB\-\-comment\fR\fIKOMENTARZ\fR .RS 4 Nowa wartość pola komentarza dla danego użytkownika w pliku hase\(/l\&. Zwykle jest zmieniana przy pomocy polecenia \fBchfn\fR(1)\&. .RE .PP \fB\-d\fR, \fB\-\-home\fR\fIKAT_DOMOWY\fR .RS 4 The user\*(Aqs new login directory\&. .sp If the \fB\-m\fR option is given, the contents of the current home directory will be moved to the new home directory, which is created if it does not already exist\&. .RE .PP \fB\-e\fR, \fB\-\-expiredate\fR\fIDATA_WAŻN\fR .RS 4 Data, od kt\('orej konto danego użytkownika zostanie wy\(/lączone\&. Data podawana jest w formacie \fIMM/DD/RR\fR\&. .sp An empty \fIEXPIRE_DATE\fR argument will disable the expiration of the account\&. .sp This option requires a /etc/shadow file\&. A /etc/shadow entry will be created if there were none\&. .RE .PP \fB\-f\fR, \fB\-\-inactive\fR\fINIEAKTYWNE\fR .RS 4 The number of days after a password expires until the account is permanently disabled\&. .sp A value of 0 disables the account as soon as the password has expired, and a value of \-1 disables the feature\&. .sp This option requires a /etc/shadow file\&. A /etc/shadow entry will be created if there were none\&. .RE .PP \fB\-g\fR, \fB\-\-gid\fR\fIGRUPA\fR .RS 4 The group name or number of the user\*(Aqs new initial login group\&. The group must exist\&. .sp Any file from the user\*(Aqs home directory owned by the previous primary group of the user will be owned by this new group\&. .sp The group ownership of files outside of the user\*(Aqs home directory must be fixed manually\&. .RE .PP \fB\-G\fR, \fB\-\-groups\fR\fIGRUPA1\fR[\fI,GRUPA2,\&.\&.\&.\fR[\fI,GRUPAN\fR]]] .RS 4 A list of supplementary groups which the user is also a member of\&. Each group is separated from the next by a comma, with no intervening whitespace\&. The groups are subject to the same restrictions as the group given with the \fB\-g\fR option\&. .sp If the user is currently a member of a group which is not listed, the user will be removed from the group\&. This behaviour can be changed via the \fB\-a\fR option, which appends the user to the current supplementary group list\&. .RE .PP \fB\-l\fR, \fB\-\-login\fR\fINOWY_LOGIN\fR .RS 4 The name of the user will be changed from \fILOGIN\fR to \fINEW_LOGIN\fR\&. Nothing else is changed\&. In particular, the user\*(Aqs home directory or mail spool should probably be renamed manually to reflect the new login name\&. .RE .PP \fB\-L\fR, \fB\-\-lock\fR .RS 4 Zablokuj has\(/lo użytkownika\&. Opcja ta powoduje wstawienie \(cq!\(cq na początku zakodowanego has\(/la\&. Opcji tej nie można używać z opcjami \fB\-p\fR or \fB\-U\fR\&. .sp Note: if you wish to lock the account (not only access with a password), you should also set the \fIEXPIRE_DATE\fR to \fI1\fR\&. .RE .PP \fB\-m\fR, \fB\-\-move\-home\fR .RS 4 Move the content of the user\*(Aqs home directory to the new location\&. .sp This option is only valid in combination with the \fB\-d\fR (or \fB\-\-home\fR) option\&. .sp \fBusermod\fR will try to adapt the ownership of the files and to copy the modes, ACL and extended attributes, but manual changes might be needed afterwards\&. .RE .PP \fB\-o\fR, \fB\-\-non\-unique\fR .RS 4 When used with the \fB\-u\fR option, this option allows to change the user ID to a non\-unique value\&. .RE .PP \fB\-p\fR, \fB\-\-password\fR\fIHAS\(/LO\fR .RS 4 The encrypted password, as returned by \fBcrypt\fR(3)\&. .sp \fBNote:\fR This option is not recommended because the password (or encrypted password) will be visible by users listing the processes\&. .sp The password will be written in the local /etc/passwd or /etc/shadow file\&. This might differ from the password database configured in your PAM configuration\&. .sp You should make sure the password respects the system\*(Aqs password policy\&. .RE .PP \fB\-R\fR, \fB\-\-root\fR \fICHROOT_DIR\fR .RS 4 Apply changes in the \fICHROOT_DIR\fR directory and use the configuration files from the \fICHROOT_DIR\fR directory\&. .RE .PP \fB\-s\fR, \fB\-\-shell\fR\fISHELL\fR .RS 4 Nazwa nowej pow\(/loki (shell) użytkownika\&. Ustawienie tego pola na puste powoduje, że system wybierze domyślną pow\(/lokę logowania\&. .RE .PP \fB\-u\fR, \fB\-\-uid\fR\fIUID\fR .RS 4 The new numerical value of the user\*(Aqs ID\&. .sp This value must be unique, unless the \fB\-o\fR option is used\&. The value must be non\-negative\&. .sp The user\*(Aqs mailbox, and any files which the user owns and which are located in the user\*(Aqs home directory will have the file user ID changed automatically\&. .sp The ownership of files outside of the user\*(Aqs home directory must be fixed manually\&. .sp No checks will be performed with regard to the \fBUID_MIN\fR, \fBUID_MAX\fR, \fBSYS_UID_MIN\fR, or \fBSYS_UID_MAX\fR from /etc/login\&.defs\&. .RE .PP \fB\-U\fR, \fB\-\-unlock\fR .RS 4 Odblokowuje has\(/lo użytkownika\&. Opcja ta powoduje usuniecie \(cq!\(cq z początku zakodowanego has\(/la\&. Opcji tej nie można używać z opcjami \fB\-p\fR lub \fB\-L\fR\&. .sp Note: if you wish to unlock the account (not only access with a password), you should also set the \fIEXPIRE_DATE\fR (for example to \fI99999\fR, or to the \fBEXPIRE\fR value from /etc/default/useradd)\&. .RE .PP \fB\-Z\fR, \fB\-\-selinux\-user\fR \fISEUSER\fR .RS 4 The new SELinux user for the user\*(Aqs login\&. .sp A blank \fISEUSER\fR will remove the SELinux user mapping for user \fILOGIN\fR (if any)\&. .RE .SH "OSTRZEŻENIA" .PP You must make certain that the named user is not executing any processes when this command is being executed if the user\*(Aqs numerical user ID, the user\*(Aqs name, or the user\*(Aqs home directory is being changed\&. \fBusermod\fR checks this on Linux, but only check if the user is logged in according to utmp on other architectures\&. .PP You must change the owner of any \fBcrontab\fR files or \fBat\fR jobs manually\&. .PP You must make any changes involving NIS on the NIS server\&. .SH "CONFIGURATION" .PP The following configuration variables in /etc/login\&.defs change the behavior of this tool: .PP \fBMAIL_DIR\fR (string) .RS 4 The mail spool directory\&. This is needed to manipulate the mailbox when its corresponding user account is modified or deleted\&. If not specified, a compile\-time default is used\&. .RE .PP \fBMAIL_FILE\fR (string) .RS 4 Defines the location of the users mail spool files relatively to their home directory\&. .RE .PP The \fBMAIL_DIR\fR and \fBMAIL_FILE\fR variables are used by \fBuseradd\fR, \fBusermod\fR, and \fBuserdel\fR to create, move, or delete the user\*(Aqs mail spool\&. .PP \fBMAX_MEMBERS_PER_GROUP\fR (number) .RS 4 Maximum members per group entry\&. When the maximum is reached, a new group entry (line) is started in /etc/group (with the same name, same password, and same GID)\&. .sp The default value is 0, meaning that there are no limits in the number of members in a group\&. .sp 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\&. .sp If you need to enforce such limit, you can use 25\&. .sp 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\&. .RE .SH "PLIKI" .PP /etc/group .RS 4 Informacje o grupach użytkownik\('ow\&. .RE .PP /etc/gshadow .RS 4 Informacje chronione o grupach użytkownik\('ow\&. .RE .PP /etc/login\&.defs .RS 4 Konfiguracja pakietu shadow\&. .RE .PP /etc/passwd .RS 4 Informacja o kontach użytkownik\('ow\&. .RE .PP /etc/shadow .RS 4 Informacje chronione o użytkownikach\&. .RE .SH "ZOBACZ TAKŻE" .PP \fBchfn\fR(1), \fBchsh\fR(1), \fBpasswd\fR(1), \fBcrypt\fR(3), \fBgpasswd\fR(8), \fBgroupadd\fR(8), \fBgroupdel\fR(8), \fBgroupmod\fR(8), \fBlogin.defs\fR(5), \fBuseradd\fR(8), \fBuserdel\fR(8)\&.
