hostname

       /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.
