git-mergetool: Explicitly use the GUI merge tool (see the `merge.guitool` config variable).

$ git mergetool --gui

try on your machine

The command "git mergetool --gui" is used to invoke a graphical user interface (GUI) tool for resolving merge conflicts during the Git merging process.

When working on a Git repository, if there are conflicting changes between branches or during a merge operation, Git will notify you about these conflicts and mark the conflicting sections within the affected files, typically showing both conflicting versions.

By executing the "git mergetool --gui" command, Git will launch a GUI tool that allows you to visually compare and merge the conflicting changes. The specific GUI tool used depends on your Git configuration, as you can set up and customize the default mergetool in Git configurations.

The GUI tool assists you in manually resolving these conflicts by providing a side-by-side comparison of the conflicting sections. You can select which version of the changes to keep or even make further modifications as necessary. Once you have resolved all conflicts, you can save the changes and exit the GUI tool, which informs Git that the conflicts have been resolved.

It's worth noting that the "git mergetool --gui" command is typically used when you prefer using a GUI tool for merging conflicts instead of resolving them directly in your text editor or terminal.
