The git merge-file command is used to merge changes from a specified file into the working directory file. This is particularly useful when you have a separate file with bug fixes and you need to incorporate those fixes into your production code. The command takes three files: the base file, the current file, and the file with changes. It then merges the changes into the current file.

Example usage:

bash

Copy code

git merge-file
