Check git user config on first local commit

#!/usr/bin/env bash

verified=$(git config --type=bool hooks.userverified)

# grab input
exec < /dev/tty

if [[ "$verified" != "true" ]]; then
    echo "Checking committer info..."

chmod +x and store in your global git templates dir :)

In case you don't have one, create a directory at any location you prefer (mine is ~/.git-templates), and set is as template dir:

mkdir -p ~/.git-templates
#...
# move this script there manually
#...
chmod +x ~/.git-templates/prepare-commit-msg
git config --global init.templatedir ~/.git-templates

This will auto-add the hook to all newly created/cloned repos, and on the first commit in each of them, ask you to verify your user information.

No more accidental commits with wrong name/email!

Small note: You should probably run git config --global init.templatedir ~/.git-templates to configure the template dir globally.

Indeed, fixed above, thx.
