This is not exactly the same as GIMP, but you might try my unix bash 
script bcimage at http://www.fmwconcepts.com/imagemagick/index.html

In IM, you can control the brightness using the -modulate function 
(as well as saturation and hue) and IM also has a -contrast function. 
(My script however, does not use either, but goes at it a more direct 
way by building a lookup table to adjust brightness and contrast)
