Fixing the issue with executing old version of script after changing etc/update-motd.d

If you are using a Linux-based operating system, you may have encountered the issue where an old version of a script is executed even after making changes to the /etc/update-motd.d directory. This can be frustrating, but fortunately, there are steps you can take to fix this problem. In this article, we will walk you through the process of resolving this issue.

Understanding the Problem

Before we dive into the solution, it's important to understand why this issue occurs. The /etc/update-motd.d directory contains scripts that are executed when a user logs into the system. These scripts generate the "Message of the Day" (MOTD) that is displayed to the user.

When you make changes to a script in the /etc/update-motd.d directory, the old version of the script may still be executed because the system caches the output of these scripts. This caching mechanism helps improve performance by avoiding the need to execute the scripts every time a user logs in.

Clearing the MOTD Cache

To fix the issue of executing the old version of a script, you need to clear the MOTD cache. Follow these steps:

1. Open a terminal window. You can usually find the terminal application in the Applications or System Tools menu.
2. Enter the following command to clear the MOTD cache:

sudo rm /var/run/motd.dynamic

This command removes the cached MOTD file, forcing the system to regenerate it the next time a user logs in.

Verifying the Fix

Once you have cleared the MOTD cache, you can verify if the issue has been resolved. Follow these steps:

1. Log out of your current session.
2. Log back in to the system.
3. Check if the changes you made to the script in the /etc/update-motd.d directory are reflected in the MOTD.

If the changes are now being displayed correctly in the MOTD, then congratulations! You have successfully fixed the issue.

Conclusion

Having an old version of a script execute even after making changes can be frustrating. However, by clearing the MOTD cache, you can ensure that the updated version of the script is executed and the changes are reflected in the MOTD.
