git diff for custom 2 files outside of any repository?

Question

I need git diff functionality for 2 files that I have outside of any repository. Is there a way to do it? Something like git diff --file1 /path/file1.txt --fi

Answer 1

If the two files are really outside of any Git repository, then Git effectively doesn't "know" anything about these files, and so git diff won't work. But, the regular Linux diff command should work. So instead of doing:

git diff /path/to/file1.txt /path/to/file2.txt

do this:

diff /path/to/file1.txt /path/to/file2.txt
