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
