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).
-y, --no-promptDo not prompt before launching a diff tool.
--promptPrompt before each invocation of the diff tool. This is the default behaviour; the option is provided to override any configuration settings.
-t <tool>, --tool=<tool>Use the diff tool specified by <tool>. Valid diff tools are: araxis, bc3, deltawalker, diffuse, emerge, ecmerge, gvimdiff, kdiff3, kompare, meld, opendiff, p4merge, tkdiff, vimdiff and xxdiff.
If a diff tool is not specified, git difftool will use the configuration variable diff.tool. If the configuration variable diff.tool is not set, git difftool 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 difftool.kdiff3.path. Otherwise, git difftool assumes the tool is available in PATH.
Instead of running one of the known diff tools, git difftool can be customized to run an alternative program by specifying the command line to invoke in a configuration variable difftool.<tool>.cmd.
When git difftool is invoked with this tool (either through the -t or --tool option or the diff.tool configuration variable) the configured command line will be invoked with the following variables available: $LOCAL is set to the name of the temporary file containing the contents of the diff pre-image and $REMOTE is set to the name of the temporary file containing the contents of the diff post-image. $MERGED is the name of the file which is being compared. $BASE is provided for compatibility with custom merge tool commands and has the same value as $MERGED.
-x <command>, --extcmd=<command>Specify a custom command for viewing diffs. git-difftool ignores the configured defaults and runs $command $LOCAL $REMOTE when this option is specified. Additionally, $BASE is set in the environment.
-g, --guiWhen git-difftool is invoked with the -g or --gui option the default diff tool will be read from the configured diff.guitool variable instead of diff.tool.
See git-diff(1) for the full list of supported options.
git difftool falls back to git mergetool config variables when the difftool equivalents have not been defined.
diff.toolThe default diff tool to use.
diff.guitoolThe default diff tool to use when --gui is specified.
difftool.<tool>.pathOverride the path for the given tool. This is useful in case your tool is not in the PATH.
difftool.<tool>.cmdSpecify the command to invoke the specified diff tool.
See the --tool=<tool> option above for more details.
difftool.promptPrompt before each invocation of the diff tool.
git-diff(1)Show changes between commits, commit and working tree, etc
git-mergetool(1)Run merge conflict resolution tools to resolve merge conflicts
git-config(1)Get and set repository or global options
