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.

open -a is nice, i use it with alias, ex:

  alias qt='open -a "quicktime player"'
  alias vlc='open -a "vlc"'

At least for me (I've installed vlc via homebrew), there is a vlc binary in the PATH, and I can just vlc <filename>

The point here is to open a document with an app not assigned as default for the given mime-type by file name extension.
