Extract filename and extension in Bash

Question

I want to get the filename (without extension) and the extension separately.

The best solution I found so far is:

NAME=`echo \"$FILE\" | cut -d\'.\'

Mellen writes in a comment on a blog post:

Using Bash, there’s also ${file%.*} to get the filename without the extension and ${file##*.} to get the extension alone. That is,

file="thisfile.txt"
echo "filename: ${file%.*}"
echo "extension: ${file##*.}"

Outputs:

filename: thisfile
extension: txt
