How to get SHA of file for specific Git commit?

Question

Is there a way to get SHA of file for specific Git commit?

It's possible with 2 commands:

1. retrieving file git show COMMIT_VERSION:myfile.txt > ~/tmp/myfile.txt
2. calculating SHA git hash-object ./tmp/myfile.txt

But, maybe there's specific command in Git that does exactly that?

Answer 1

git ls-tree COMMIT_VERSION myfile.txt在其第三个字段中似乎包含相同的结果。
