HOSTNAME(5)                         hostname                         HOSTNAME(5)



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.
