As the two commands take many of the same options, you are probably 
right. “git log -1 -p” looks like a good start.

Yes. There is also “git diff --cached” (--staged is an alias of --cached 
here) which shows the diff between the commit (HEAD by default) and the 
index / staging area.

(One annoying feature of git is the great variation in terminology. It 
seems they have moved to new (and better?) terminology over time, but 
the old terminology remains, so that you now have to learn two or three 
synonymous terms for many concepts.)
