batch image compression on ubuntu (lossy)

Question

Its strange but I cannot find a good image compression tool (ala IrfanView on windows) on ubuntu to recompress images in order to save disk space (yes! I care about it :)).

I am looking for web standard image details.

Earlier, I had used digikam but it doesnt support recompression nowadays (tools->recompress doesnt exist)

Gimp : no batch mode of recompression

jpegoptim, adept : few details regarding parameters to specify for optimal use.

trimage : hangs on my system (desktop froze for compressing 600+ images).

Any other ?

Ubunto doesn't run batch files which are Windows files. Please remove the tag. — Serenity, Apr 11 '15 at 05:12
@Serenity, you got me wrong. I didnt mention execing windows batch files in ubuntu. but recompressing list of image files. — everCurious, Jul 18 '15 at 19:23
