How can I compare the most recent commit with the previous commit?

How can I compare my most recent commit with the previous commit? I'd like to know the diff between 83a853349d91c855442c and 35ad2211a1cc7d0dbd49 (without having to specify the actual commit sha)

$ git log
commit 83a853349d91c855442c
Author: Jagat<[email protected]>
Date:   Thu Aug 22 11:44:27 2019 -0700

You can use a bare git show for the most recent commit. From the docs:

For commits it shows the log message and textual diff. It also presents the merge commit in a special format as produced by git diff-tree --cc.

You need two things:

  • The latest commit in the current branch is pointed by HEAD. In your example, 83a853349d91c855442c.
  • One of the ways to point to the first previous commit is <rev>^ (if there are multiple parent commits, use <rev>^<n> to point to the n-th parent). In your example, HEAD^ points to 35ad2211a1cc7d0dbd49.

Therefore:

git diff HEAD^ HEAD

git diff HEAD~1 HEAD

HEAD~1 is the penultimate commit (1 is the index), while HEAD refers to the most recent committed state.
