Pipe filelist into 'git add'

I performed a fresh clone and copied/pasted a working directory into the cloned directory. Now have a list of changed files: $ git status --short | grep -v "??" | cut -d " " -f 3 GNUmakefile Readme.txt base32.h base64.h ... When I try to get Git to add them, it results in an error (I don't care about adding 1 at a time): $ git status --short | grep -v "??" | cut -d " " -f 3 | git add Nothing specified, nothing added. Maybe you wanted to say 'git add .'? Adding the -: $ git status --short | grep -v "??" | cut -d " " -f 3 | git add - fatal: pathspec '-' did not match any files And --: $ git status --short | grep -v "??" | cut -d " " -f 3 | git add -- Nothing specified, nothing added. Maybe you wanted to say 'git add .'? Trying to use *interactive* from the man page appears to have made a greater mess of things: $ git status --short | grep -v "??" | cut -d " " -f 3 | git add -i staged unstaged path 1: unchanged +1/-1 GNUmakefile 2: unchanged +11/-11 Readme.txt ... *** Commands *** 1: status 2: update 3: revert 4: add untracked 5: patch 6: diff 7: quit 8: help Huh (GNUmakefile)? What now> *** Commands *** 1: status 2: update 3: revert 4: add untracked 5: patch 6: diff 7: quit 8: help Huh (Readme.txt)? (I've already deleted the directory Git made a mess of, so I'm not trying to solve that issue). How do I tell Git to add the files piped into it?
