i was wondering if bluestacks and greenshot have linux alternitives.

i use bluestacks for android emulation (with camera support, sound, and notifications)
i use greenshot for quick screenshots (hotkey to activate selection of screen then auto-save to pc and upload to imgur and copy link to clipboard)

does anyone know of any software that can do this? i have tried a few but im mostly confused on installation via the terminal as i'm a noob and am used to .exe files.
