See 'man git':

"Porcelain" commands are *not* for use in scripts; their output may change. git diff, git status, git commit, git checkout are in this category.

"Plumbing" commands are for use in scripts and their output will not change. git ls-files, git diff-tree, git diff-files are in this category.
