Launch quicklook from the command line in full screen mode Is it possible to launch quicklook from the command line in full screen? qlmanage does not seem to have any option for that.
This is probably not what you meant, but you could reveal the file in Finder and emulate pressing option-space:

open -R .; osascript -e 'tell app "System Events" to keystroke space using option down' -e 'tell app "Finder" to close window 1'
