GIT-DIFFTOOL(1)GIT-DIFFTOOL(1)NAMEgit-difftool - Show changes using common diff tools
SYNOPSIS
git difftool [<options>] <commit>{0,2} [--] [<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.
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 con-
figuration settings.
-t <tool>, --tool=<tool>
Use the diff tool specified by <tool>. Valid merge tools are:
kdiff3, kompare, tkdiff, meld, xxdiff, emerge, vimdiff, gvimd-
iff, ecmerge, diffuse, opendiff, p4merge and araxis.
If a diff tool is not specified, git difftool will use the con-
figuration 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 vari-
ables 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.

GIT-DIFFTOOL(1)GIT-DIFFTOOL(1)-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.
