HOSTNAME(5) /etc/hostname HOSTNAME(5)NAME
hostname - Local host name configuration file
SYNOPSIS
/etc/hostname
DESCRIPTION
The /etc/hostname file configures the name of the local system that is set during boot, with the sethostname(2) system call. It should
contain a single newline-terminated host name string. The host name may be a free-form string up to 64 characters in length, however it is
recommended that it consists only of 7bit ASCII lower-case characters and no spaces or dots, and limits itself to the format allowed for
DNS domain name labels, even though this is not a strict requirement.
Depending on the operating system other configuration files might be checked for configuration of the host name as well, however only as
fallback.
HISTORY
The simple configuration file format of /etc/hostname originates from Debian GNU/Linux.

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
