install-hooks.sh

#!/bin/bash
# Installs the IDEasy git hooks for THIS clone.
#
# It points git's core.hooksPath at the version-controlled git-hooks/ directory.
# This is repo-local and fully isolated: it writes only to .git/config of this clone,
# never to your global git config, and cannot affect any other repository on your machine.
# When core.hooksPath is set, git ignores .git/hooks entirely (the generated *.sample files
# are left untouched).
#
# Run once per clone. On Windows use Git Bash (comes with Git for Windows):
#   ./install-hooks.sh
#
# Uninstall with:
#   git config --unset core.hooksPath
