Show Commit from Other Branch
I wanted to view a commit on a different branch without having to checkout/switch to that branch. It turns out git show can do that!
Say I'm on branch-a, but I want to see the latest commit I made on branch-b. It's actually really straightforward:
$ git show branch-b
This follows a lot of the git norms, too! git show branch-b~ will show the previous commit on branch-b (and git show branch-b~2 the commit before that). To view a single file in that commit, git show branch-b:path/to/file.rb!
