Inventory untracked files

Before you begin

• Python 3.12 or later.
• Git must be installed on PATH. --repo must be an existing non-bare repository.

Set up your example

1. Save as git-untracked-file-report.py.
2. Open a terminal in its folder.
3. Run python "git-untracked-file-report.py" --help and prepare the listed input files.

This recipe uses your own local input or creates its own example output. Follow the setup steps below.

Download the ZIP, extract it, and open a terminal inside the extracted folder. The source file is git-untracked-file-report.py.

Run the script

python "git-untracked-file-report.py"

If your system uses python3 instead of python, use that command for Python examples. Keep paths containing spaces in quotes. Required inputs and optional settings are described in the code and setup steps.

How it works

1. List nonignored untracked files and byte counts without staging anything.
2. Arguments are explicit and expected input errors produce a message with a nonzero exit code.
3. Results reflect your selected local data or the specific endpoint you choose; the example illustrates the result shape.

Make it your own

Adapt the task

Add a suffix filter after decoding name if only a particular file class matters.

Adjust presentation

Edit final print statements or json.dumps indentation to adjust the report layout. Keep input validation and exclusive-create file modes intact.

Change one setting at a time, run it again on sample data, and compare the output. The customization guide walks through this process.
