How a function changed from beginning - git trick

Come across this nice git trick  to know how a function evolved:

git log -L :<Function_name>:<Filename>

So,  it start with the first edition of the function followed by all changes done within the function.

git show commit

// show the first two patches in git branch
git show HEAD -2


// show the top one
git show HEAD
equivalent to
git show HEAD -1
