How to get diff working like git-diff?

I like the output formatting of git diff. The color and the +/- representation of changes between lines is easier to read than GNU diff.

I can run git diff using --no-index flag outside of a git repo and it works fine. However, it appears to be missing the --exclude option for excluding files or subdirectories from a recursive diff.

Is there a way to get the best of both worlds? (color options and +/- format of git diff and --exclude option of GNU diff).

I've experimented with colordiff, but I still prefer the output format of git diff

Solution

  • This will do the +/- rather than < and >.

    diff -u file1 file2

    Since GNU diffutils 3.4 the flag --color has been added. Combining both makes the following:

    diff --color -u file1 file2

    The flag --color also takes an argument, valid options are never, always, or auto. Useful when you want to be more explicit on what needs to be done.
