[SOLVED] Remove extension from image

Dafydd · 08-29-2014, 07:42 PM

I would like to strip the extension from the end of the image name for use elsewhere in an html file. There a very large number of pictures and I want to use this in a scrip that will also write the HTML code.

This code snippet dose not perform as I understand the example on Stack Overflow.

Code:

 http://stackoverflow.com/questions/125281/how-do-i-remove-the-file-suffix-and-path-portion-from-a-path-string-in-bash

Two days I've read the internet and tried differenet things, nothing has worked. Can someone help?

Thanks
Dave

Code Snippet:

Code:

#! /bin/bash
for image_name in *.jpeg *.jpg *.JPG *.gif *.GIF *.png *.PNG; 
	do
			echo "$image_name"; ##trouble shoot
		image_type=${image_name%.}
			echo "$image_type"; ##trouble shoot
	done;

This is the screen output I get:

I'm sure there are a million ways.

Might look at this while you are at it.

Your script appears to have added files instead of removing them.

That's because you transcribed it incorrectly.

Code:

		image_type=${image_name%.*}

You may also wish to look into the following as an item to place in your script:

Code:

shopt -s nullglob

This solved my problem. I feel embarrested for staring at that for hours and not noticing I typoed it.

Thank you.
