The command git log --oneline --raw -n 1 shows the files modified in the last commit.

This is a sample output:

Notice how there are different kinds of results: the fifth column (the single letter) denotes whether the file was added, deleted, etc. There's more information in the official docs.

In general, I don't care for deletions. Just additions, modifications and renames.

Take this file, for example:

:100644 100644 345935a be5cbf6 M        tiddlers/now.tid

It is a modification, and I want the filepath (tiddlers/now.tid).

But the next is unnecessary: the file is not on the tiddlers folder.
