Please become accustomed to provide decent context info of your problem.
It is always helpful to carefully and detailedly phrase a request, and to support it with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

MACHINE-INFO(5) machine-info MACHINE-INFO(5)NAME
machine-info - Local machine information file
SYNOPSIS
/etc/machine-info
DESCRIPTION
The /etc/machine-info file contains machine meta data.
The basic file format of machine-info is a newline-separated list of environment-like shell-compatible variable assignments. It is possible
to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported, allowing
applications to read the file without implementing a shell compatible execution engine.
/etc/machine-info contains meta data about the machine that is set by the user or administrator.
Depending on the operating system other configuration files might be checked for machine information as well, however only as fallback.
OPTIONS
The following machine meta data parameters may be set using /etc/machine-info:
PRETTY_HOSTNAME=
A pretty human-readable UTF8 machine identifier string. This should contain a name like Lennart's Laptop which is useful to present to
the user and does not suffer by the syntax limitations of internet domain names. If possible the internet host name as configured in
/etc/hostname should be kept similar to this one. Example: if this value is Lennart's Computer an Internet host name of
lennarts-computer might be a good choice. If this parameter is not set an application should fall back to the Internet host name for
presentation purposes.
ICON_NAME=
An icon identifying this machine according to the XDG Icon Naming Specification[1]. If this parameter is not set an application should
fall back to computer or a similar icon name.
EXAMPLE
PRETTY_HOSTNAME="Lennart's Computer"
ICON_NAME=computer-laptop
