# @title WSL Dedup Repos
# @description Remove duplicate directories from /mnt/d/Git that also exist in ~/git
# @author ropean, Claude Sonnet (Anthropic)
# @version 1.0.0
#
# Compares Windows-side git repos (default: /mnt/d/Git) against WSL-side repos
# (default: ~/git) and, after confirmation, deletes the Windows-side copies of
# any directory that already exists on the WSL side.

# @example
#   ./wsl-dedup-repos.sh

# @requires bash, rimraf
