git-restage: Ensure all diffs in currently staged files are staged.

git-restage

#!/bin/sh

# Stage all diffs found in currently staged files

# This is useful if you've got a set of files ready to commit, but edited one
# or more of them (via prettier, delinting, deleting debug statements, adding
# more tests, ...), and want to make sure those changes are included.

# Usage: `git restage`

# Installation: add this script to your $PATH and chmod +x.

# Hop down to the root of the repository so paths are correct:
cd "$(git rev-parse --show-toplevel)" || exit 1

# For all currently staged files, call `git stage`:
git diff --name-only --cached | xargs --verbose -n 1 -- git stage
