Complete Guide to Clean and Optimize Ubuntu (Linux)

Introduction

Keeping your Ubuntu (Linux) operating system clean and optimized is crucial for ensuring optimal performance and efficient storage space usage. In this guide, you will learn how to clean Ubuntu by removing temporary files, obsolete packages, old logs, and more.

Step 1: Cleaning Caches and Temporary Files

First, let's clean caches and temporary files that accumulate unnecessary space on your hard drive.

Using System Cleaner Tools (Stacer, BleachBit):

Install Stacer with:

sudo apt install stacer

Using Command Line:

sudo apt clean
sudo apt autoremove --purge -y
sudo rm -rf /tmp/*

Step 2: Removing Obsolete Packages

After cleaning caches, we'll remove packages that are no longer needed on your system.

sudo apt autoremove --purge -y

Step 3: Cleaning Old Logs

Old logs can take up significant space on your disk. Let's remove old compressed logs.

sudo rm -rf /var/log/*.gz

Step 4: Removing Obsolete Configuration Files

Sometimes, applications leave obsolete configuration files. It's good to review and remove them.

# Review and remove obsolete configuration files in ~/.config as needed.

Step 5: Cleaning Browser History (Optional)

If you use browsers like Firefox, clean their history and cache to free up additional space.

# Example to clean Firefox history:
# firefox --headless --clear-history

Step 6: Reviewing Disk Usage

Finally, review how your disk is being used after cleaning.

df -h

Conclusion

With these simple yet effective steps, you can keep your Ubuntu clean and optimized, ensuring better performance and efficient disk space management. Perform this cleanup regularly to maintain your system in optimal condition.
