|
|
\fBuseradd\fR
|
|
command creates a new user account using the values specified on the command line and the default values from the system. Depending on command line options, the useradd command will update system files and may also create the new user's home directory and copy initial files.

|
|
.TP 3n
|
|
\fB\-c\fR, \fB\-\-comment\fR\fIKOMMENTAR\fR

|
|
\fB\-b\fR, \fB\-\-base\-dir\fR \fIBASE_DIR\fR
|
|
The default base directory for the system if
|
|
\fB\-d\fR
|
|
dir is not specified.
|
|
\fIBASE_DIR\fR
|
|
is concatenated with the account name to define the home directory. If the

|
|
The new user will be created using
|
|
\fIHOME_DIR\fR
|
|
as the value for the user's login directory. The default is to append the
|
|

|
|
name to
|
|
\fIBASE_DIR\fR
|
|
and use that as the login directory name. The directory
|
|
\fIHOME_DIR\fR
|
|
does not have to exist but will not be created if it is missing.

|
.TP 3n
|

|
|
\fI/etc/default/useradd\fR.

|
|
option is used, otherwise the files contained in
|
|
\fI/etc/skel\fR
|
|
will be used instead. Any directories contained in
|
|
\fISKEL_DIR\fR
|
|
or
|
|
\fI/etc/skel\fR
|
|
will be created in the user's home directory as well. The
|
|
