Git Difftool Command

git-difftool(1) =============== NAME ---- git-difftool - Show changes using common diff tools SYNOPSIS -------- [verse] '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 linkgit:git-diff[1]. OPTIONS ------- -d:: --dir-diff:: Copy 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. --rotate-to=<file>:: Start showing the diff for the given path, the paths before it will move to the end and output. --skip-to=<file>:: Start showing the diff for the given path, skipping all the paths before it. -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

The git-difftool command is a Git frontend to git diff, allowing users to compare and edit files between revisions using common diff tools, with various options for customization and configuration, including directory diff, prompting, and tool selection, enabling flexible and efficient file comparison and editing.
