Question

我尝试使用git grep -i 'search' README.md并且输出找到了一些我感兴趣的行，但是这些行没有打印出git sha，因此我可以获得有关这些提交的更多信息。输出看起来像这样：

README.md:ElastiCache, ElasticSearch, and RDS setup with Terraform

如何查看此行的git sha？我查看了文档，它甚至没有包含“commit”或“sha”这个词。

如果没有其他规范，git grep只会查看当前的提交。

要查看其他提交（或索引），您必须为其命名（或使用--cached）。例如，比较：

$ git grep asdf
Documentation/rev-list-options.txt:  ``asdf'', and a file `quux` exists with con
t/t5516-fetch-push.sh:  test_must_fail git push >.git/bar --porcelain asdfasdfas
t/t9100-git-svn-basic.sh:       echo asdf > dir &&
t/t9132-git-svn-broken-symlink.sh:asdf
t/t9132-git-svn-broken-symlink.sh:test_expect_success SYMLINKS '"bar" is a symli
t/t9132-git-svn-broken-symlink.sh:      (cd x && test xasdf = x"$(git cat-file b

VS

$ git grep asdf HEAD^ HEAD~3

如果列出多个树（或提交ID）进行搜索，结果会以您的说明符为前缀，以便您知道它们与哪一个一起使用。
