Finding out JPG compression level, without using save-as

I would like to know of a Linux program that will let me know the JPG compression level, either through the command line or GUI. I prefer the command line using ImageMagick.

With GIMP it appears that you have to Save-As to find out what the JPG compression level was, I prefer to check image properties but that doesn't give you the JPG compression level in GIMP.

thanks.

try

identify -verbose yourimage

...

Compression: JPEG
Quality: 80


The quality is the compression level
