sorry if this question exists, I surprisingly could not find it :/
How can I perform a git diff between two files within the same branch & same commit?
i.e. git diff fileA.php fileB.php
(ideally with the easy to read color coding that git offers….or similar to what the program BeyondCompare does!)
You don’t need git for that, just use
diff fileA.php fileB.php(or vimdiff if you want side by side comparison)
