git - Emacs：为什么 shell 命令“git log”有效，但“git shortlog”无效？

Question

我想不通。为什么这些行为不同：

(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 但什么也不打印。这是为什么？

还

1. 两者都可以完美地git log工作git shortlogansi-term
2. 两者都git log发出git shortlog警告，但仍在工作shell

Answer 1

man git-shortlog

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.

You must explicitly provide reference to work in your case,

Use, git shortlog HEAD instead.
