Обнулим файл 

cat /dev/null > /etc/motd

Зайдем в него 

nano /etc/motd

И скопируем предварительно созданный текст с сайта 

http://patorjk.com/software/taag/#p=display&f=Graffiti&t=Type%20Dyagilev%20

Перейдем в папку

cd /etc/profile.d
nano sshinfo.sh

И добавим в файл sshinfo.sh скрипт

SystemMountPoint="/";

LinesPrefix="  ";

b=$(tput bold); n=$(tput sgr0);

SystemLoad=$(cat /proc/loadavg | cut -d" " -f1);

ProcessesCount=$(cat /proc/loadavg | cut -d"/" -f2 | cut -d" " -f1);

MountPointInfo=$(/bin/df -Th $SystemMountPoint 2>/dev/null | tail -n 1);

MountPointFreeSpace=( \

  $(echo $MountPointInfo | awk '{ print $6 }') \

  $(echo $MountPointInfo | awk '{ print $3 }') \

);

UsersOnlineCount=$(users | wc -w);

UsedRAMsize=$(free | awk 'FNR == 3 {printf("%.0f", $3/($3+$4)*100);}');

SystemUptime=$(uptime | sed 's/.*up \([^,]*\), .*/\1/'); 

if [ ! -z "${LinesPrefix}" ] && [ ! -z "${SystemLoad}" ]; then

  echo -e "${LinesPrefix}${b}System load:${n}\t${SystemLoad}\t\t\t${LinesPrefix}${b}Processes:${n}\t\t${ProcessesCount}";

fi;

if [ ! -z "${MountPointFreeSpace[0]}" ] && [ ! -z "${MountPointFreeSpace[1]}" ]; then

  echo -ne "${LinesPrefix}${b}Usage of $SystemMountPoint:${n}\t${MountPointFreeSpace[0]} of ${MountPointFreeSpace[1]}\t\t";

fi;

echo -e "${LinesPrefix}${b}Users logged in:${n}\t${UsersOnlineCount}";

if [ ! -z "${UsedRAMsize}" ]; then

  echo -ne "${LinesPrefix}${b}Memory usage:${n}\t${UsedRAMsize}%\t\t\t";

fi;

echo -e "${LinesPrefix}${b}System uptime:${n}\t${SystemUptime}";

Добавим прав 

chmod +x /etc/profile.d/sshinfo.sh
