How to Create a Custom Linux MOTD Screen

Creating a custom Message of the Day (Linux MOTD) screen on Linux involves modifying certain files and configurations. We’ll use the /etc/update-motd.d/ directory to add scripts that fetch and display relevant information.

Here’s the detailed procedure:

Step 1: Access the Terminal and Check MOTD is installed

Open a terminal on your Linux system.

Bash
sudo apt-get install --reinstall update-motd

Step 2: Backup Existing Linux MOTD and Update Scripts (Optional)

Backup the existing MOTD file and update scripts:


The Message of the Day (MOTD) in Linux is typically stored in the “/etc/motd” file. In some versions of Ubuntu and Debian, it’s located in “/etc/update-motd.d”.

Bash
sudo cp /etc/motd /etc/motd_backup 
sudo cp -r /etc/update-motd.d/ /etc/update-motd.d_backup

Step 3: Create Custom Linux MOTD Scripts

Create custom scripts in the /etc/update-motd.d/ directory to fetch and display dynamic information. For example, create a script named 10-custom-info:

Bash
sudo nano /etc/update-motd.d/10-custom-info

Add the following content to the script:

Bash
#!/bin/bash

# Fetch system information
WHO=$(who)
CPU=$(top -bn1 | grep "Cpu(s)" | sed "s/.*, *\([0-9.]*\)%* id.*/\1/" | awk '{print 100 - $1}')
DISK=$(df -h / | awk 'NR==2 {print $5}')
RAM=$(free -m | awk 'NR==2 {print $3}')

# Display information
echo "Welcome to Your Custom MOTD"
echo "============================="
echo "Who is logged on: $WHO"
echo "CPU Usage: $CPU%"
echo "Disk Usage: $DISK"
echo "RAM Usage: $RAM MB"

Save the script and make it executable:

Bash
sudo chmod +x /etc/update-motd.d/10-custom-info

Step 4: Edit the MOTD File

Edit the main MOTD file to include a reference to the custom scripts:

Bash
sudo nano /etc/motd

Add the following line at the end of the file:

Bash
cat /etc/update-motd.d/10-custom-info

Step 5: Save and Exit

Save the MOTD file and exit the text editor.

Step 6: Test the MOTD

Log out and log back in, or open a new terminal window. Your custom MOTD with dynamic system information should now be displayed.

Step 7: Optional – Update MOTD

Some systems may require you to update the MOTD manually:

Bash
sudo update-motd

Now, each time a user logs in, they’ll see dynamic system information in the MOTD, including who is logged on, CPU usage, disk usage, and RAM usage. Feel free to customize the script further to include additional information if needed.
