A diff utility takes in two files and command-line arguments and compares them for changes. The changes are then shown as output indication what has changed where.

Any version of Python 3 is good enough to run this program. Additionally the rich package is required. Install it via the terminal.

pip install rich

Or

pip install -r requirements.txt

Run the program from the terminal as follows:

python diff.py <file1.txt> <file2.txt>

Or on Linux do:

./diff.py <file1.txt> <file2.txt>
