git - Get information about a SHA-1 commit object?

Question

I searched for a topic of interest in a commit log:

$ git log --pretty=oneline | grep -i ...

$SHA1 < ... commit message ... >

I now have a SHA1, and I want to know information about the files affecting that SHA1 and maybe later diff them with their parent. How can I get this done?

Answer 1

git show <SHA1> will show the commit date, author, parent, and diff of files that changed from parent commit.
