This allows users to be present in central database (such as NIS, kerberos or LDAP) without using a distributed file system or pre\-creating a large number of directories\&. The skeleton directory (usually /etc/skel/) is used to copy default files and also sets a umask for the creation\&. .PP The new users home directory will not be removed after logout of the user\&. .SH "OPTIONS" .PP \fBsilent\fR .RS 4 Don\*(Aqt print informative messages\&. .RE .PP \fBumask=\fR\fB\fImask\fR\fR .RS 4 The user file\-creation mask is set to \fImask\fR\&.
