The NetworkManager text user interface tool nmtui can be used to query and set the static host name in the /etc/hostname file.

Important

In Red Hat Enterprise Linux, NetworkManager uses the systemd-hostnamed service to read and write the static host name, which is stored in the /etc/hostname file. Due to this, manual modifications done to the /etc/hostname file are no longer picked up automatically by NetworkManager; you should change the system host name through the hostnamectl utility. Also, the use of the HOSTNAME variable in the /etc/sysconfig/network file is now deprecated.
