LinuxQuestions.org - [SOLVED] Bash script: How to test string value?

Apologies for such a basic question, but I keep reading about bash and trying different things to no avail.

I have this script that I run on a number of selected files. The pathnames of the files are passed to the script in value $*. For every selected file with the type extension of .DNG, a zenity dialog should come up. Here's the script:

Code:

#!/bin/bash

for x in $*

do

        if [ "$x" = "*.DNG" ]

                then zenity --info --text="$x"

        fi

done

exit 0

My test [ "$x" = "*.DNG" ] is obviously wrong. But I've tried it without quotes and it also doesn't work. How should this be stated to work?
