Implement shell tools in Python:
Overview
This PR starts the Python implementation of shell tools by adding the cat command.
It is the first step in the implement-shell-tools-with-python branch, separate from the Node.js version.
Changes
Added cat/cat.py script.
Implemented functionality to:
Print file contents.
-n → number all lines.
-b → number only non-blank lines.
Handle multiple files and glob patterns (*.txt).
Added cat/sample-files/ directory with sample .txt files for testing.
Usage
Run from the project root:
python3 cat/cat.py cat/sample-files/1.txt
python3 cat/cat.py -n cat/sample-files/1.txt
python3 cat/cat.py -b cat/sample-files/3.txt
python3 cat/cat.py cat/sample-files/*.txt
Next Steps
Add Python implementations for ls and wc.
