git whatchanged - -M 做什么？

Question

我正在查看一些使用传递给 Git 的 -M(大写 M，而不是小写，记录为包含 merge )标志的代码，这发生了变化。

我在手册页(对于 1.8.3.1)中看不到标志的定义。谁能建议它的作用？它是-m(小写)的反义词吗？

doc 是 git 日志。 git whatchanged 已弃用。请改用 git log。

-M --find-renames[=]

If generating diffs, detect and report renames for each commit.

For following files across renames while traversing history, see --follow.

If n is specified, it is a threshold on the similarity index (i.e. amount of addition/deletions compared to the file’s size). For example, -M90% means Git should consider a delete/add pair to be a rename if more than 90% of the file hasn’t changed. Without a % sign, the number is to be read as a fraction, with a decimal point before it. I.e., -M5 becomes 0.5, and is thus the same as -M50%. Similarly, -M05 is the same as -M5%. To limit detection to exact renames, use -M100%.

The default similarity index is 50%.
