git-difftool - Show changes using common diff tools
git difftool [<options>] [<commit> [<commit>]] [--] [<path>...:]
git difftool is a Git command that allows you to compare and edit files between revisions using common diff tools. git difftool is a frontend to git diff and accepts the same options and arguments. See git-diff(1).
Copy the modified files to a temporary location and perform a directory diff on them. This mode never prompts before launching the diff tool.
Do not prompt before launching a diff tool.
Prompt before each invocation of the diff tool. This is the default behaviour; the option is provided to override any configuration settings.
Start showing the diff for the given path, the paths before it will move to end and output.
Start showing the diff for the given path, skipping all the paths before it.

will pick a suitable default.
You can explicitly provide a full path to the tool by setting the configuration variable
difftool.<tool>.path. For example, you can configure the absolute path to kdiff3 by setting
