Few additions.

open -n file.pdf : opens new instance of Preview application which is useful if you want to open the same file twice (for example to look at different pages at once).

caffeinate -d : prevents display turning off, useful if you want to look at display without moving mouse.

I use this all the time:

open -a <GUI Application> <File>

Handy for distinguishing between editing and consuming media.
