This program is a minimal clone of the UNIX diff program.

diff.py takes two file names as command-line arguments and compares them for changes.

• Rich: rich==10.11.0

Running on Windows:

python diff.py <orignal_file> <changed_file> 

Running on Linux / macOS:

./diff.py <orignal_file> <changed_file> 

Consider two files v1 and v2:

v1:

Bruce Alfred Jason 

v2:

Batman Alfred Red Hood Joker Ra's Al Ghul 

On running ./diff.py v1 v2, you'll get the following output:

 [-] Line 1: Bruce [+] Line 1: Batman [-] Line 3: Jason [+] Line 3: Red Hood [+] Line 4: Joker [+] Line 5: Ra's Al Ghul
