Emacs:为什么 shell 命令“git log"有效，但“git shortlog"不是吗? [英] Emacs: why shell-command "git log" works, but "git shortlog" doesn't?

问题描述

我想不通.为什么这些行为不同:

I can't figure this out. Why do these behave differently:

(shell-command "git log")
(shell-command "git shortlog")

第一个按预期工作:返回 0 并将内容打印到 shell 输出缓冲区.第二个返回 0 但不打印任何内容.这是为什么?

First one works as expected: returns 0 and prints stuff to shell output buffer. Second one returns 0 but prints nothing. Why is that?

还有

1. git log 和 git shortlog 在 ansi-term
中都能完美运行
2. git log 和 git shortlog 都给出警告，但在 shell
中仍然有效

1. both git log and git shortlog work perfectly in ansi-term
2. both git log and git shortlog give a warning but still work in shell

推荐答案

man git-shortlog

如果没有在命令行和任一标准上传递修订输入不是终端或没有当前分支，git shortlog 会输出从标准输入读取的日志摘要，不参考当前存储库.

If no revisions are passed on the command line and either standard input is not a terminal or there is no current branch, git shortlog will output a summary of the log read from standard input, without reference to the current repository.

您必须明确提供您案例中工作的参考，

You must explicitly provide reference to work in your case,

使用，git shortlog HEAD 代替.
