# OneDNS
> Smart DNS Switcher for Linux with Backup and Restore
> Written in pure Bash — minimal, fast, and efficient.
## 🚀 About
**OneDNS** is a lightweight command-line tool for managing DNS settings on Linux systems.
It allows you to switch DNS providers with one click, reset to default, and safely restore your original settings from backup.
## 🔧 Features
- ✅ System-wide installation or live usage (no install needed)
- ✅ Switch between trusted DNS providers (403, Electro, Shecan)
- ✅ Reset to Google DNS (8.8.8.8)
- ✅ Automatic backup of original `/etc/resolv.conf`
- ✅ Easy restore of backup anytime
- ✅ Clean uninstallation option
- 🛑 "Filter check" feature is present in code (commented out for now)
## 📦 Installation
### Live mode (no installation):
```bash
sudo bash onedns.sh
```
### Install system-wide:
When prompted, select:
```
[1] Install (system-wide)
```
Then use it from anywhere with:
```bash
sudo onedns
```
## 💻 Usage
You’ll see a menu like this:
```
[1] Start DNS Options
[2] Reset DNS (8.8.8.8)
[5] About
[6] Show Current DNS
[7] Restore Original DNS from Backup
[9] Uninstall OneDNS
[00] Exit

### DNS Options:

- **Shecan** → Reliable Iranian DNS provider
## 🧠 Backup & Restore
The script creates a **one-time backup** of `/etc/resolv.conf` when you first change the DNS.
To restore it at any time, select:
```
