NAME         top

       git-merge-index - Run a merge for files needing merging

SYNOPSIS         top

       git merge-index [-o] [-q] <merge-program> (-a | [--] <file>*)

DESCRIPTION         top

       This looks up the <file>(s) in the index and, if there are any merge
       entries, passes the SHA-1 hash for those files as arguments 1, 2, 3
       (empty argument if no file), and <file> as argument 4. File modes for
       the three files are passed as arguments 5, 6 and 7.

OPTIONS         top

           Do not interpret any more arguments as options.

           Run merge against all files in the index that need merging.

           Instead of stopping at the first failed merge, do all of them in
           one shot - continue with merging even when previous merges
           returned errors, and only return the error code after all the

           Do not complain about a failed merge program (a merge program
           failure usually indicates conflicts during the merge). This is
           for porcelains which might want to emit custom messages.

       If git merge-index is called with multiple <file>s (or -a) then it
       processes them in turn only stopping if merge returns a non-zero exit

       Typically this is run with a script calling Git’s imitation of the
       merge command from the RCS package.

       A sample script called git merge-one-file is included in the

       ALERT ALERT ALERT! The Git "merge object order" is different from the
       RCS merge program merge object order. In the above ordering, the
       original is first. But the argument order to the 3-way merge program
       merge is to have the original in the middle. Don’t ask me why.


           torvalds@ppc970:~/merge-test> git merge-index cat MM
           This is MM from the original tree.                    # original
           This is modified MM in the branch A.                  # merge1
           This is modified MM in the branch B.                  # merge2
           This is modified MM in the branch B.                  # current contents


           torvalds@ppc970:~/merge-test> git merge-index cat AA MM
           cat: : No such file or directory
           This is added AA in the branch A.
           This is added AA in the branch B.
           This is added AA in the branch B.
           fatal: merge program failed

       where the latter example shows how git merge-index will stop trying
       to merge once anything has returned an error (i.e., cat returned an
       error for the AA file, because it didn’t exist in the original, and
       thus git merge-index didn’t even try to merge the MM thing).
