OS-Flip 🌀

A Linux terminal tool to view, set, and flip your default boot OS.

---

✨ Overview

OS Flip is a Python-based utility to manage boot preferences on Linux systems using GRUB2. Whether you're running a dual-boot setup or switching between multiple Linux distributions, OS Flip gives you a simple terminal UI to:

• 🔍 View bootable OS entries
• ✅ Set the default OS
• 🔁 Temporarily flip into another OS for one-time boot

---

🖥️ Platforms Supported

• 🐧 Linux only (GRUB2-based bootloaders)

Windows and macOS are not supported. Windows does not allow GRUB changes, and macOS/Boot Camp setups are incompatible. Any Linux distribution should manage BIOS/UEFI defaults through firmware settings.

📝 Custom Shortcuts (Advanced)

1. Using a Text File

You can automate OS Flip actions using a simple text file shortcut. For example, create a text file named win_boot.txt containing:

2
1
y

Meaning:

• 2 → Choose Flip OS
• 1 → Select OS option 1 (e.g., Windows Boot Manager) for one-time boot
• y → Confirm and reboot immediately

Run it with:

sudo os-flip < win_boot.txt

---

2. Create a Quick Command (Alias)

To make this even faster, add a shortcut to your shell configuration file (~/.bashrc, ~/.zshrc, etc.):

alias flip='sudo os-flip < /path/to/win_boot.txt'

After saving and reloading your shell (source ~/.bashrc), just type:

flip

…and your system will instantly flip and reboot into the selected OS.
