How to add all files to stage whose file path is given in a file

Question

Let's say I have a file files_to_stage.txt having file paths like

src/a/a1.txt
src/a/a2.txt
src/b/b3.txt
src/b/b6.txt
src/c/c5.txt

Now I want to stage all files having paths present in files_to_stage.txt for instance src/a/a1.txt, src/a/a2.txt etc.

How can I do it? I am looking for something like

git add -f files_to_stage.txt

Answer 1

git add $(cat files_to_stage.txt)

should be enough.

The subcommand (the $() construct) reads out your file and sends it to git add.
