GIT-DIFFTOOL(1) Git Manual GIT-DIFFTOOL(1)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 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, --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 git-diff(1)

git-mergetool(1)
Run merge conflict resolution tools to resolve merge conflicts
git-config(1)
Get and set repository or global options
