Iterating/recursing over files in a directory. 'Find' is more powerful and flexible.

# Method #1:  Recursive 'find' w/it's powerful -OPTIONS filtering
#   and then piping the results to a 'while' command for performing
#   multiple file-by-file actions.
#
# Only explore this folder level
# Only return "dotfiles"
find . -maxdepth 1 -name ".*" | while read fname; do

    echo $name
    echo ~/$name
    echo $HOME/$name

# Method #2:  'For-loop' over an 'ls' result
# This way to iterate is simpler, but doesn't quite work
#   for most fine-grained filtering.
