Linuxar Optimization Tool

A tool to optimize your Linux system by cleaning junk files and applying performance tweaks.

Overview

Linuxar is a bash script designed to help you optimize your Linux system through cleanup of junk files, system cache clearing, and performance improvements. With a straightforward menu interface, you can choose between optimizing your system or restoring previous settings if needed. This tool is ideal for system administrators and enthusiasts looking to give their Linux machine a performance boost with minimal hassle.

Features

• System Cleanup:

  • Clears package manager caches (supports APT, DNF, and Pacman).
  • Removes temporary files from /tmp and /var/tmp.
  • Cleans user caches and truncates older log files.
  • Drops system caches for memory cleanup.

• Performance Tweaks:

  • Adjusts kernel parameters via /etc/sysctl.conf (e.g., vm.swappiness, vfs_cache_pressure, etc.).
  • Changes filesystem mount options to improve performance (adding noatime,discard for ext4).
  • Configures zRAM for enhanced memory management.
  • Applies CPU governor tweaks by setting the CPU frequency scaling governor to "performance".
  • Optimizes disk I/O settings (e.g., enabling TRIM for SSDs or setting the HDD scheduler to "deadline").
  • Reduces GRUB timeout to speed up booting.
  • Installs additional performance tools such as preload and haveged to further enhance system responsiveness.

• Restore Functionality:
  A built-in restore option lets you revert back to the original system settings if the tweaks are not to your liking, ensuring you can experiment safely.

• Logging & Backups:
  Every operation is logged and important configuration files (like sysctl.conf and fstab) are backed up before changes are applied. This makes it easy to audit adjustments or perform a full restoration.

• User-Friendly Menu:
  Comes with an eye-catching, color-coded text menu that provides clear options:

  • Optimize System – Clean junk and apply performance tweaks.
  • Restore Previous Settings – Revert your system to its previous configuration.
  • Exit – Quit the tool.

Installation

1. Clone the Repository

   git clone https://github.com/White9shadow/linuxar.git
   cd linuxar

2. Set Script Permissions

   Ensure that the script is executable:

   chmod +x linuxar.sh

3. Run as Root

   Since Linuxar needs root privileges to modify system files and settings, run it with sudo:

   sudo ./linuxar.sh

🛠️ HOW TO INSTALL .deb FILE IN LINUX

Assume your file is:
linuxar_1.0-1.deb

✅ Option 1: Using dpkg (manual method)

sudo dpkg -i linuxar_1.0-1.deb

Then fix any missing dependencies (if needed):

sudo apt -f install

---

✅ Option 2: Using apt (recommended)

sudo apt install ./linuxar_1.0-1.deb

✅ This automatically handles dependencies and is cleaner than dpkg.

---

📂 If the file is in Downloads:

cd ~/Downloads
sudo apt install ./linuxar_1.0-1.deb

---

🔍 To Check Installation:

dpkg -l | grep linuxar

[Note] renmae linuxar_1.0-1.deb with linuxar_xxx.deb

❌ To Uninstall the Package:

sudo apt remove linuxar

Usage

Once executed, Linuxar presents a user-friendly menu with the following options:

• Optimize System:
  When selected, the script will:

  • Clean out junk and temporary files.
  • Apply various performance tweaks to kernel and disk settings.
  • Adjust system services and enable/disable additional tools.
  • Log all operations in a dedicated log file located in your backup directory (~/linuxar_bckup).

• Restore Previous Settings:
  If any modifications do not suit your needs or cause issues, you can revert the changes using the restoration feature. This function uses the backups created before applying tweaks.

• Exit:
  Simply terminates the script.

• deb linuxar
