.SH SYNOPSIS
.ft CW

.SH DESCRIPTION
\f(CWsetuname\f1

.P
.PD 1
.TP
\f(CW\-s\f1

underbar, and dollar sign.
.TP
\f(CW\-n\f1
Changes the node name.
\f2node\f1 specifies the new network 
node name and can consist
of alphanumeric characters and the special characters dash,
underbar, and dollar sign.
.TP
\f(CW-t\f1
Temporary change.
No attempt will be made to create a permanent change.
.P
Either or both the \f(CW-s\f1 and \f(CW-n\f1 options must be
given when invoking \f(CWsetuname\f1.
.P
The system architecture may place requirements on the
size of the system and network node name.
The command will issue a fatal warning message
and an error message
if the name entered is incompatible with
the system requirements.
.SH NOTES
\f(CWsetuname\f1
attempts to change the parameter values in two places:
the running kernel and,
as necessary per implementation,
to cross system reboots.
A temporary change changes only the running kernel.
