Just few steps!
Install figlet package:
|
1 |
yum install figlet |
Create /etc/motd.sh script with this content:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
#!/bin/sh # clear figlet -f slant $(hostnamectl --pretty) printf "\n" printf "\t- %s\n\t- Kernel %s\n" "$(cat /etc/redhat-release)" "$(uname -r)" printf "\n" date=`date` load=`cat /proc/loadavg | awk '{print $1}'` root_usage=`df -h / | awk '/\// {print $(NF-1)}'` memory_usage=`free -m | awk '/Mem:/ { total=$2 } /buffers\/cache/ { used=$3 } END { printf("%3.1f%%", used/total*100)}'` swap_usage=`free -m | awk '/Swap/ { printf("%3.1f%%", "exit !$2;$3/$2*100") }'` users=`users | wc -w` time=`uptime | grep -ohe 'up .*' | sed 's/,/\ hours/g' | awk '{ printf $2" "$3 }'` processes=`ps aux | wc -l` ethup=$(ip -4 ad | grep 'state UP' | awk -F ":" '!/^[0-9]*: ?lo/ {print $2}') ip=$(ip ad show dev $ethup |grep -v inet6 | grep inet|awk '{print $2}') echo "System information as of: $date" echo printf "System load:\t%s\tIP Address:\t%s\n" $load $ip printf "Memory usage:\t%s\tSystem uptime:\t%s\n" $memory_usage "$time" printf "Usage on /:\t%s\tSwap usage:\t%s\n" $root_usage $swap_usage printf "Local Users:\t%s\tProcesses:\t%s\n" $users $processes echo [ -f /etc/motd.tail ] && cat /etc/motd.tail || true |
Make the script executable:
|
1 |
chmod +x /etc/motd.sh |
Append this script to /etc/profile in order to be executed as last command once a user logs in:
|
1 |
echo "/etc/motd.sh" >> /etc/profile |
Try and have fun! 🙂
