git-mergetool:tldr:29c6a

The command "git mergetool --tool ${tool_name}" is used to invoke a visual merge tool while resolving conflicts during a Git merge.

Here's an explanation of the components of the command:

• "git mergetool": This is the main command that tells Git to launch the merge tool.
• "--tool": This option is used to specify the merge tool that you want to use. It is followed by the argument ${tool_name}.
• "${tool_name}": This is a placeholder for the name of the desired merge tool you want to use. You can replace ${tool_name} with the actual name of the merge tool you want to use, like "kdiff3", "meld", "vimdiff", etc.

For example, if you want to use the merge tool "kdiff3" to resolve conflicts, you would use the command:

git mergetool --tool kdiff3

This command will open up the specified merge tool and allow you to visually compare and merge conflicting changes in your Git repository.
