Git Config Diff

Git config diff is a command that allows you to set the default diff tool for Git. For example, if you want to set the default diff tool to vimdiff, you can use the following command:

git config --global diff.tool vimdiff

The --global option allows you to set the diff tool for all repositories on your computer. If you want to set the diff tool for a specific repository, you can omit the --global option.

After you have set the diff tool, you can use the following command to run the diff tool:

git difftool file-or-commit-hax1 file-or-commit-hax2

Or setting diff as alias is also a good idea:

git config --global alias.d difftool

Then you can use the following command to run the diff tool:

git d file-or-commit-hax1 file-or-commit-hax2

You can set the alias in the .gitconfig file as well:

~/.gitconfig

[alias]
    d = difftool --tool=vimdiff
