#!/bin/bash

# Installation:
#
# 1.   nano /etc/ssh/sshd_config
#      PrintMotd no
#
# 2.   nano /etc/profile
#      /usr/bin/dynmotd # Place at the bottom
#
# 3.   Then of course drop this file at
#      /usr/bin/dynmotd
#
# 4.   Enter here your temperature device:
#       an example it is for me "cpu_thermal-virtual-0"
#

# config
sensor="cpu_thermal-virtual-0"

hi, how you did the rocky linux fonts ?

@teymurov27 I used ASCII art font called "ANSI Shadow" which generated from Patorjk's online tool.

thanks.
