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\'.\'          


        

Answer 1

Simply use ${parameter%word}

In your case:

${FILE%.*}

If you want to test it, all following work, and just remove the extension:

FILE=abc.xyz; echo ${FILE%.*};
FILE=123.abc.xyz; echo ${FILE%.*};
FILE=abc; echo ${FILE%.*};
