This script gets all your commits on the main/master branch from all subfolders in the given base-directory. Useful for getting an overview of your work, i.e., for creating job references.

# ==============================================================================
# Script: get_my_commits.sh
# Description:
#   Finds and displays Git commits by a specific author on the main/master
#   branch across multiple Git repositories within a base directory.
#   Excludes merge commits.
#
# Usage:
#   ./get_my_commits.sh [base_directory] [author_email]
#
# Arguments:
#   base_directory (Optional): Path to directory containing Git repos. Defaults to '~/dev/sources'.
#   author_email   (Optional): Author's email. Defaults to global Git config user.email.
# ==============================================================================

# --- Configuration ---

# Use 'eval' to correctly expand ~ in the path, if present
eval BASE_DIR="$BASE_DIR_INPUT"

# Attempt to retrieve the email from global Git config if not provided as $2
AUTHOR_EMAIL="${2:-$(git config --global --get user.email)}"

# --- Pre-run Checks ---
