Git Merge File

git-merge-file(1) ================= NAME ---- git-merge-file - Run a three-way file merge SYNOPSIS -------- [verse] 'git merge-file' [-L <current-name> [-L <base-name> [-L <other-name>]]] [--ours|--theirs|--union] [-p|--stdout] [-q|--quiet] [--marker-size=<n>] [--[no-]diff3] [--object-id] <current> <base> <other> DESCRIPTION ----------- Given three files `<current>`, `<base>` and `<other>`, 'git merge-file' incorporates all changes that lead from `<base>` to `<other>` into `<current>`. The result ordinarily goes into `<current>`. 'git merge-file' is useful for combining separate changes to an original. Suppose `<base>` is the original, and both `<current>` and `<other>` are modifications of `<base>`, then 'git merge-file' combines both changes. A conflict occurs if both `<current>` and `<other>` have changes in a common segment of lines. If a conflict is found, 'git merge-file' normally outputs a warning and brackets the conflict with lines containing <<<<<<< and >>>>>>> markers. A typical conflict will look like this: <<<<<<< A lines in file A ======= lines in file B >>>>>>> B If there are conflicts, the user should edit the result and delete one of the alternatives. When `--ours`, `--theirs`, or `--union` option is in effect, however, these conflicts are resolved favouring lines from `<current>`, lines from `<other>`, or lines from both respectively. The length of the conflict markers can be given with the `--marker-size` option. If `--object-id` is specified, exactly the same behavior occurs, except that instead of specifying what to merge as files, it is specified as a list of object IDs referring to blobs. The exit value of this program is negative on error, and the number of conflicts otherwise (truncated to 127 if there are more than that many conflicts). If the merge was clean, the exit value is 0. 'git merge-file' is designed to be a minimal clone of RCS 'merge'; that is, it implements all of RCS 'merge''s functionality which is needed by linkgit:git[1]. OPTIONS -------

The git-merge-file command is used to perform a three-way file merge, incorporating changes from one file into another, and is useful for combining separate changes to an original file. It takes three files as input, including the current file, base file, and other file, and resolves conflicts by bracketing them with markers, allowing the user to edit and resolve the conflicts manually or automatically using options such as --ours, --theirs, or --union.
