rename-files_to-folder.sh

#!/bin/bash
# SYPOPSIS: Rename files in folder to match folder.
# CREDIT: Unamed user on superuser or superadmin. If you find this, let me know and I will add you to the credits.

find * -type f -maxdepth 1 | while read file
do
    dirname="$(dirname "$file")"
    new_name="${dirname##*/}"
    file_ext=${file##*.}
    if [ -n "$file_ext" -a  -n "$dirname" -a -n "$new_name" ]

This script was tested on Ubuntu 16.10 and Debian 8.8. I have not had the chance to test on other system but do have friends and colleagues who will test on various platforms. All that is in use is basic bash scripting, find and mv.
