Automatically remove stale modules (based on last-modified date)

clean_modules.sh

# Remove stale modules directories, fast!
#
# Paste or source this file in your shell rc file (should work with Bash and ZSH)
#
#   Optionally provide a path as first arg, and optionally a duration in days as second arg (default=30)
#     e.g. clean_modules ~/github 60
#   Remove the "-exec du" line for faster operation (i.e. do not print sizes, which can be slow)
PROJECT_DIR=~/Projects

# If `bfs` is installed, use that for faster searching
if type "bfs" > /dev/null; then
  FINDER=bfs

  FINDER=find
