git log --exit-code是什么意思？ [英] What does git log --exit-code mean?

问题描述

git-log 手册页将-check 选项描述为与-exit-code 选项不兼容。我想知道-退出代码的含义，但我在任何地方都找不到。我试过 man git log ， man git ，Google并在此处直接搜索...无济于事！

The git-log man page describes the --check option as incompatible with the --exit-code option. I'd like to know what this --exit-code means but I can't find it anywhere. I've tried man git log, man git, Google and direct search here on SO... to no avail!

-退出代码对 git log ？

推荐答案

TL; DR

TL; DR

我想知道这-退出代码的含义[...]

-退出代码是 diff-* ¹ 选项，如果有更改，该选项使Git命令以 1 退出，并且 0 否则。

--exit-code is a diff-*¹ option that makes the Git command exit with 1 if there are changes, and 0 otherwise.

[...]但我找不到它

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

您可以在 git-diff 手册页中了解它。 （仅在传递 git-log 手册页时提及）。

You can read about it in the git-diff man page (it's only mentioned in passing in the git-log man page).

-check 和-exit-code git-diff 手册页（更具体地说，在 Documentation / diff-options.txt ）：

Both --check and --exit-code are described in the git-diff man page (more specifically, in Documentation/diff-options.txt):

   --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，尽管不是全部， diff -* 选项与 git-log 兼容。 -check 选项是，而-exit-code 选项不是，如下所示提交消息来自 Git项目存储库：

Some, though not all, diff-* options are compatible with git-log. The --check option is, whereas the --exit-code option is not, as hinted at by the following commit message from the Git-project repository:

docs：不要提及-quiet 或-exit-code 在git-log（1）

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

这些是 diff 选项，但在 log 没有意义。 $ c>。

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

（1） _{diff-* 立场<瓷器 git-diff 所基于的管道命令。}

(1) _{diff-* stands for the plumbing commands that porcelain git-diff is based on.}
