NAME
       git-difftool - Show changes using common diff tools

SYNOPSIS
       git difftool [<options>] [<commit> [<commit>]] [--] [<path>...]

DESCRIPTION
       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).

OPTIONS
       -y, --no-prompt
           Do not prompt before launching a diff tool.

       --prompt
           Prompt 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 merge tools are: kdiff3, kompare, tkdiff, meld, xxdiff, emerge, vimdiff,
           gvimdiff, ecmerge, diffuse, opendiff, p4merge and araxis.

           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, --gui
           When 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.

CONFIG VARIABLES
       git difftool falls back to git mergetool config variables when the difftool equivalents have not been defined.

       diff.tool
           The default diff tool to use.

       diff.guitool
           The default diff tool to use when --gui is specified.

       difftool.<tool>.path
           Override the path for the given tool. This is useful in case your tool is not in the PATH.

       difftool.<tool>.cmd
           Specify the command to invoke the specified diff tool.

           See the --tool=<tool> option above for more details.

       difftool.prompt
           Prompt before each invocation of the diff tool.

SEE ALSO
