git - How to commit only the file names listed in an external file

Question

I have a source tree with a bunch of modifications. I selected a big list of files and put then into a file. Is there a way to commit only these ones?

I want something like:

git commit --files "/tmp/files-to-commit.txt" -m "Fixed bug"

Answer 1

git add `cat /tmp/files-to-commit.txt`
git commit -m "Fixed bug"

The `` do shell expansion. So if you have the names of files in a file, cat'ing them out will list them as args.
