GIT-MERGE-INDEX(1)

NAME
git-merge-index - Runs a merge for files needing merging

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

DESCRIPTION
This looks up the <file>(s) in the index and, if there are any merge entries, passes the SHA1 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..sp

OPTIONS

—   Do not interpret any more arguments as options.

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

-o  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 merges are over.

-q  Do not complain about failed merge program (the merge program failure usually indicates conflicts during 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 code..sp Typically this is run with the a script calling the merge command from the RCS package..sp A sample script called "git-merge-one-file" is included in the distribution..sp 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..sp Examples:.sp

    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
    or.sp

    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 (ie "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)..sp
