git-merge-one-file

Merge changes from another branch into one file

SYNOPSIS

git merge-one-file

PARAMETERS


    The name of the branch containing the changes to merge into the specified file.


    The path to the file that will be merged with the changes from the specified branch. The path is relative to the top level of the working tree.

DESCRIPTION

The `git-merge-one-file` command is a specialized tool designed to merge changes from one or more remote branches into a specific file within your local repository. It's particularly useful when you want to integrate changes for a single file without affecting the rest of your project's codebase.

Unlike `git merge`, which merges entire branches, `git-merge-one-file` targets only a single file. It avoids creating a merge commit in the repository history, instead directly modifying the file in your working directory and staging area. This operation is beneficial when you need to integrate changes quickly and cleanly into a single file while minimizing the impact on the overall repository history. It's important to use this command with caution, as it modifies the working directory directly, and improper use can lead to unintended consequences. It should be used carefully when integrating partial features or bug fixes contained within specific files from remote branches.

CAVEATS

This command directly modifies your working directory and staging area. It does not create a merge commit. Back up your file before using this command to prevent data loss. Use with caution to avoid unintended side effects.

WORKFLOW

A typical workflow would involve: 1) `git fetch` to update your remote tracking branches, 2) `git merge-one-file ` to merge the changes, 3) resolve any conflicts if necessary, 4) `git add ` to stage the changes, and 5) `git commit` to commit the merged file.

CONFLICT RESOLUTION

If the command encounters conflicts during the merge, it will mark the conflicting sections in the specified file with standard conflict markers (<<<<<<<, =======, >>>>>>>). You must manually resolve these conflicts by editing the file, removing the markers, and choosing the correct content. After resolving the conflicts, stage the file using `git add`.

STAGING AREA

The effect on the staging area is important: the merged file is automatically placed into the staging area. After using `git-merge-one-file`, you need to examine the file, eventually correct it and `git commit`.
