NAME¶
git-difftool - Show changes using common diff toolsSYNOPSIS¶
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¶
-d, --dir-diffCopy the modified files to a temporary location and
perform a directory diff on them. This mode never prompts before launching the
diff tool.
-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 values
include emerge, kompare, meld, and vimdiff. Run git difftool --tool-help for
the list of valid <tool> settings.
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.
--tool-help
Print a list of diff tools that may be used with
--tool.
--[no-]symlinks
git difftool's default behavior is create symlinks
to the working tree when run in --dir-diff mode and the right-hand side of the
comparison yields the same content as the file in the working tree.
Specifying --no-symlinks instructs git difftool to create copies instead.
--no-symlinks is the default on Windows.
-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.toolThe 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.

conflicts
