This project provides a Python script and GitHub Actions workflow for scanning text files in a specified directory for lines matching a given regular expression.

The script.py file contains a Python script that:

1. Takes two command-line arguments:
   • A full path to a directory
   • A regular expression pattern
2. Scans all .txt files in the specified directory
3. Outputs the filename and line number of the first line in each file that matches the regular expression

The .github/workflows/scan_files.yml file defines a GitHub Actions workflow that:

1. Runs on pushes to the main branch or can be manually triggered
2. Sets up a Python environment
3. Creates a test directory with sample text files
4. Runs the scanning script
5. Displays the results directly in the GitHub Actions console output

You can manually trigger the workflow from the Actions tab in the GitHub repository. When doing so, you can specify:

• The directory to scan (default: './test_directory')
• The regular expression to use (default: 'example.*pattern')

1. Clone this repository
2. Ensure script.py is in the root directory
3. Create the .github/workflows directory if it doesn't exist
4. Place the scan_files.yml workflow file in the .github/workflows directory
5. Push these changes to your GitHub repository

After the workflow runs (either automatically on push or manually triggered):

1. Go to the Actions tab in your GitHub repository
2. Click on the specific workflow run
3. In the workflow run summary, expand the "Run scanner script" step
4. The scan results will be visible directly in the log

We can modify the script.py file to change how files are scanned or results are reported.
