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.
You may use
hostnamectl(1) to change the value of this file from the
command line.
HISTORY¶
The simple configuration file format of /etc/hostname originates from Debian
GNU/Linux.
