HOSTNAME(5)                       hostname                       HOSTNAME(5)

NAME         top

       hostname - Local hostname configuration file

SYNOPSIS         top


DESCRIPTION         top

       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         top

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