arman

Found the actual codes executed in /usr/lib/armbian-config/jobs.sh, when you run
sudo armbian-config Basically, it updates /etc/hostname, /etc/hosts
Here is my wrapped function:
change_hostname() { # modified from /usr/lib/armbian-config/jobs.sh # should be OK for debian as well(?) local hostname_current=$(cat /etc/hostname) if [[ -z $1 ]]; then echo "Current hostname: $hostname_current" else local hostname_new=$1 sudo sed -i "s/$hostname_current/$hostname_new/g" /etc/hosts sudo sed -i "s/$hostname_current/$hostname_new/g" /etc/hostname # Temporarily change the hostname for the current session sudo hostname "$hostname_new" sudo systemctl restart systemd-logind.service echo "Logout to make effective the new hostname: $hostname_new" fi }
