Update Nov 2020:
To get the list of files modified (and committed!) in the current branch you can use the shortest console command using standard git:
git diff --name-only master...
If your local "master" branch is outdated (behind the remote), add a remote name (assuming its "origin")
git diff --name-only origin/master...
If you want to include uncommitted changes as well, remove the ...
:
git diff --name-only master
If you use different main branch name (eg: "main"), substitute it:
git diff --name-only origin/main...
If your want to output to stdout (so its copyable)
git diff --name-only master... | cat
per really nice detailed explanation of different options https://blog.jpalardy.com/posts/git-how-to-find-modified-files-on-a-branch/
