NAME
setuname - changes machine information
SYNOPSIS
setuname {-s name | -n node} [-t]
DESCRIPTION
setuname changes the parameter value for the system name and node
name. Each parameter can be changed using setuname and the appropriate
option.
OPTIONS
-s Changes the system name. name specifies new system name and can
consist of alphanumeric characters and the special characters
dash, underscore, and dollar sign. The first character must be an
alpha character.
Note:
If the system name is changed, a new installation or update ins-
tallation of the system cannot be carried out successfully.
-n Changes the node name. node specifies the new network node name
and can consist of alphanumeric characters and the special char-
acters dash, underscore, and dollar sign.
-t Temporary change. No attempt will be made to create a permanent
change.
Either or both the -s and -n options must be given when invoking
setuname.
The system architecture may place requirements on the size of the sys-
tem and network node name. The command will issue a fatal warning mes-
sage and an error message if the name entered is incompatible with the
system requirements.
LOCALE
The LCMESSAGES environment variable governs the language in which
message texts are displayed.
The LCCTYPE environment variable governs character classes, character
conversion (shifting) and the behavior of character classes in regular
expressions.
If LCMESSAGES or LCCTYPE is undefined or is defined as the null
string, it defaults to the value of LANG. If LANG is likewise unde-
fined or null, the system acts as if it were not internationalized.
If any of the locale variables has an invalid value, the system acts
as if none of the variables was set.

The LCALL environment variable governs the entire locale. LCALL
takes precedence over all the other environment variables which affect
internationalization.
NOTES
setuname 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.
