How to add prefix in filename for multiple files?

I have many jpg files on the server and would like to add my abc_ prefix to them, is there an easy way to do this without renaming them manually?

Example:
image01.jpg to abc_image01.jpg

Thanks guys

Is there also code to remove something from a filename?

Like for example all my files in one directory are called xx.avi.flv - I just want to remove the .avi part in the filename

 

Just modify the script by Mohie to do your job. The principles are the same for adding and for subtracting info from a file name.
