posiada następujące opcje:
.PP
\fB\-a\fR, \fB\-\-all\fR
.RS 4
Add the user to the supplementary group(s)\&. 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

.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

.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

.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
