Add signedoff-by message to all git commits via a git hook

README.md

Getting started

Add the following signedoff-by git hook using the following steps:

1. Create a new file (from above) and add it to the project's git folder .git/hooks/commit-msg
2. Make the hook executable

chmod +x .git/hooks/commit-msg

commit-msg

#!/bin/sh

NAME=$(git config user.name)
EMAIL=$(git config user.email)

if [ -z "$NAME" ]; then
    echo "empty git config user.name"
    exit 1
fi

if [ -z "$EMAIL" ]; then
    echo "empty git config user.email"
    exit 1
fi

git interpret-trailers --if-exists doNothing --trailer \
    "Signed-off-by: $NAME <$EMAIL>" \
    --in-place "$1"
