GIT-MERGE-INDEX(1) Git Manual GIT-MERGE-INDEX(1)NAME
git-merge-index - Run a merge for files needing merging
SYNOPSIS
git-merge-index [-o] [-q] <merge-program> (-a | [--] <file>*)
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.
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.
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
distribution.
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.
Examples:
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
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).
