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.
Do not prompt before launching a diff tool.
Prompt before each invocation of the diff tool. This is the default behaviour; the option is provided to override any configuration settings.
- -t <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.toolis 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
When git difftool is invoked with this tool (either through the
--tooloption or the
diff.toolconfiguration variable) the configured command line will be invoked with the following variables available:
$LOCALis set to the name of the temporary file containing the contents of the diff pre-image and
$REMOTEis set to the name of the temporary file containing the contents of the diff post-image.
$MERGEDis the name of the file which is being compared.
$BASEis provided for compatibility with custom merge tool commands and has the same value as
- -x <command>
Specify a custom command for viewing diffs. git-difftool ignores the configured defaults and runs
$command $LOCAL $REMOTEwhen this option is specified. Additionally,
$BASEis set in the environment.
When git-difftool is invoked with the
--guioption the default diff tool will be read from the configured
diff.guitoolvariable instead of
See git-diff for the full list of supported options.
