📝 Title: Best Practices to Set the LD_LIBRARY_PATH Environmental Variable Permanently in Linux

✨ Introduction: Welcome, tech enthusiasts! 🚀 Are you struggling with setting the LD_LIBRARY_PATH environmental variable permanently in Linux? We feel your pain! 😔 But fret not, because in this blog post, we'll walk you through common issues that arise when setting this variable and provide easy solutions to overcome them. By the end, you'll be equipped with the knowledge to set the LD_LIBRARY_PATH variable permanently, ensuring it survives terminal restarts. Let's dive right in! 🤓

🔍 Common Issue: A common issue readers encounter after setting the LD_LIBRARY_PATH variable is that it disappears upon terminal restart. 😱 So, how can we make sure our changes stick around permanently? 🤔

💡 Solution: To set the LD_LIBRARY_PATH variable permanently, we need to modify the .bashrc file instead of the .bash_profile. The .bash_profile file is only read for login shells, while the .bashrc file is loaded for interactive shells too. 😎

📚 Step-by-Step Guide: Here's a step-by-step guide on how to permanently set the LD_LIBRARY_PATH in Linux:

1️⃣ Open your terminal and type:

vi ~/.bashrc

2️⃣ Scroll down to the end of the file using the arrow keys.

3️⃣ Press i to enter the "Insert" mode.

4️⃣ Add the following lines at the end of the .bashrc file:

LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH

5️⃣ Press the Esc key to exit the "Insert" mode.

6️⃣ Type :wq and press Enter to save and exit the file.

7️⃣ Restart your terminal for the changes to take effect. 🔄

💡 Pro Tip: If you're unsure where to find the .bashrc file, you can also try modifying the .bash_profile file as mentioned in the original context. However, keep in mind that this solution may not work for every Linux distribution.

🎉 Congratulations! You have successfully set the LD_LIBRARY_PATH variable permanently in Linux! 🎉 Now, let's validate if the changes were applied correctly.

🔍 Verification: 1️⃣ Open your terminal.

2️⃣ Type the following command:

echo $LD_LIBRARY_PATH

3️⃣ If the path /usr/local/lib is displayed, congratulations! You've successfully set the LD_LIBRARY_PATH variable and made it permanent. 🥳

4️⃣ If nothing is displayed or the incorrect path is shown, please revisit the step-by-step guide and ensure you followed each step correctly. Don't worry; mistakes happen to the best of us! Just give it another shot. 💪
