setuname(1M) UNIX System V(Essential Utilities) setuname(1M)
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.
The options and arguments for this command are:
-s Changes the system name. name specifies new system name and can
consist of alphanumeric characters and the special characters dash,
underbar, and dollar sign.
-n Changes the node name. node specifies the new network node name
and can consist of alphanumeric characters and the special
characters dash, underbar, 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 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.
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.
