git log --exit-code 是什么意思？

Question

git-log man page 将 --check 选项描述为与 --exit-code 选项不兼容。我想知道这个 --exit-code 是什么意思，但我到处都找不到。我试过 man git log、man git、Google 并直接在此处搜索...无济于事！

--exit-code 对 git log 意味着什么？

Answer 1

它在 git-diff docs 中提到（并且显然不打算与 git-log 一起使用）：

"Make the program exit with codes similar to diff(1). That is, it exits with 1 if there were differences and 0 means no differences."

Answer 2

TL;博士

I'd like to know what this --exit-code means [...]

--exit-code 是一个 diff-*¹ 选项，它使 Git 命令在有更改时以 1 退出，和 0 否则。

[...] but I can't find it anywhere.

您可以在 git-diff 手册页中阅读它（它仅在 git-log 手册页中被提及）。

--check 和 --exit-code 都在 git-diff 手册页中进行了描述（更具体地说，在 Documentation/diff-options.txt 中）：

   --check
 Warn if changes introduce whitespace errors. What are considered
 whitespace errors is controlled by core.whitespace configuration.
 By default, trailing whitespaces (including lines that solely
 consist of whitespaces) and a space character that is immediately
 followed by a tab character inside the initial indent of the line
 are considered whitespace errors. Exits with non-zero status if
 problems are found. Not compatible with --exit-code.

和

   --exit-code
 Make the program exit with codes similar to diff(1). That is, it
 exits with 1 if there were differences and 0 means no differences.

有些 diff-* 选项与 git-log 兼容，但不是全部。 --check 选项是，而 --exit-code 选项不是，正如以下 commit message from the Git-project repository:

所暗示的

docs: don't mention --quiet or --exit-code in git-log(1)

These are diff-options, but they don't actually make sense in the context of log.

(1) _{diff-* 代表 porcelain git-diff 所基于的管道命令。}
