# Queuing System Shell Scripts

This repository contains a set of shell scripts for managing Android devices running the HMG QLine application in a multi-device hospital environment. The scripts automate deployment, logging, restarting, and uninstallation tasks for efficient device management.

## Features
- **Deploy APKs:** Install and launch specific versions of the QLine app on multiple devices.
- **Restart App:** Force-stop and relaunch the QLine app on all connected devices.
- **Uninstall App:** Remove the QLine app from all connected devices.
- **Extract Logs:** Pull log files from devices for troubleshooting and analysis.
- **Device Connection:** Automatically connect to devices over Wi-Fi using IP addresses.

## Folder Structure
```
queuing_system/
├── apks/                # APK files for different QLine app versions
├── logs/                # Data logs from devices
├── connect_devices.sh   # Script to connect to devices
├── deploy_qline.sh      # Script to deploy APKs
├── device_ips.txt       # List of device IP addresses
├── extract_logs.sh      # Script to extract logs from devices
├── restart_qline.sh     # Script to restart the app on devices
├── uninstall_qline.sh   # Script to uninstall the app
```

## Getting Started
1. **Clone the repository:**
   ```bash
   git clone <repo-url>
   cd queuing_system 
   ```
2. **Configure device IPs:**
    - Add device IPs to a file (e.g., `device_ips_all.txt`), one per line.
3. **Prepare APKs:**
    - Place APK files in the `apks/` folder, named as per the versioning scheme.
4. **Run scripts:**
    - Make scripts executable: `chmod +x *.sh`
    - Example: Deploy APKs
      ```bash
      ./deploy_qline.sh
      ```
    - Example: Extract logs from a device
      ```bash
      sh extract_logs.sh -ip <device_ip:port>
      ```

## Script Commands (One by One)
Use the commands below with the appropriate IP list file.

### Connect Devices
```bash
sh connect_devices.sh -ipfile device_ips_all.txt
```

### Deploy QLine APK
```bash
sh deploy_qline.sh -ipfile device_ips_all.txt -version 9.2
```

**Deploy to Single IP:**
```bash
echo "10.70.6.143" > temp_ip.txt
sh deploy_qline.sh -ipfile temp_ip.txt -version 9.2
rm temp_ip.txt
```

### Restart QLine App
```bash
sh restart_qline.sh -ipfile device_ips_all.txt
```

### Uninstall QLine App
```bash
sh uninstall_qline.sh -ipfile device_ips_all.txt
```

### Extract Logs (Single Device)
```bash
sh extract_logs.sh -ip <device_ip:port>
```

### Extract Logs (All Devices)
```bash
sh extract_all_logs.sh -ipfile device_ips_all.txt
```

### Clear Logs (Single Device)
```bash
sh clear_logs.sh -ip <device_ip:port>
```

### Clear Logs (All Devices)
```bash
sh clear_logs_all.sh -ipfile device_ips_all.txt
```

### Kill QLine App (All Devices)
```bash
sh kill_qline.sh -ipfile device_ips_all.txt
```

## Requirements
- macOS (tested)
- Android SDK Platform Tools (adb)
- Wi-Fi connection to devices

## Notes
- Ensure all devices are on the same Wi-Fi network (`Cloud Solutions`).
- APKs and logs are ignored from version control via `.gitignore`.
- Scripts are designed for hospital multi-floor deployments but can be adapted for other environments.
