SYNOPSIS

-'git fmt-merge-msg' [--log | --no-log] <$GIT_DIR/FETCH_HEAD
-'git fmt-merge-msg' [--log | --no-log] -F <file>
+'git fmt-merge-msg' [-m <message>] [--log | --no-log] <$GIT_DIR/FETCH_HEAD
+'git fmt-merge-msg' [-m <message>] [--log | --no-log] -F <file>
DESCRIPTION
-----------
Synonyms to --log and --no-log; these are deprecated and will be
removed in the future.
+-m <message>::
+--message <message>::
+ Use <message> instead of the branch names for the first line
+ of the log message. For use with `--log`.
+
-F <file>::
--file <file>::
Take the list of merged objects from <file> instead of
index ce5b369985c254ec5d986aa3dd250828cf3cc4cb..eedef1bb1a14591d23b1fe6e93da1e3c2be2786b 100644 (file)
SYNOPSIS
--------
-'git merge-base' [-a|--all] <commit> <commit>...
+[verse]
+'git merge-base' [-a|--all] [--octopus] <commit> <commit>...
+'git merge-base' --independent <commit>...
DESCRIPTION
-----------
ancestor', i.e. a 'merge base'. Note that there can be more than one
merge base for a pair of commits.
-Among the two commits to compute the merge base from, one is specified by
-the first commit argument on the command line; the other commit is a
-(possibly hypothetical) commit that is a merge across all the remaining
-commits on the command line. As the most common special case, specifying only
-two commits on the command line means computing the merge base between
-the given two commits.
+Unless `--octopus` is given, among the two commits to compute the merge
+base from, one is specified by the first commit argument on the command
+line; the other commit is a (possibly hypothetical) commit that is a merge
+across all the remaining commits on the command line. As the most common
+special case, specifying only two commits on the command line means
+computing the merge base between the given two commits.
As a consequence, the 'merge base' is not necessarily contained in each of the
commit arguments if more than two commits are specified. This is different
--all::
Output all merge bases for the commits, instead of just one.
+--octopus::
+ Compute the best common ancestors of all supplied commits,
+ in preparation for an n-way merge. This mimics the behavior
+ of 'git show-branch --merge-base'.
+
+--independent::
+ Instead of printing merge bases, print a minimal subset of
+ the supplied commits with the same ancestors. In other words,
+ among the commits given, list those which cannot be reached
+ from any other. This mimics the behavior of 'git show-branch
+ --independent'.
