NAME

       hostname - Local hostname configuration file

SYNOPSIS

       /etc/hostname

DESCRIPTION

       The /etc/hostname file configures the name of the local system that is set during boot using the
       sethostname(2) system call. It should contain a single newline-terminated hostname string. Comments
       (lines starting with a `#') are ignored. The hostname may be a free-form string up to 64 characters in
       length; however, it is recommended that it consists only of 7-bit 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.

       You may use hostnamectl(1) to change the value of this file during runtime from the command line. Use
       systemd-firstboot(1) to initialize it on mounted (but not booted) system images.

HISTORY

       The simple configuration file format of /etc/hostname originates from Debian GNU/Linux.
