Ive got handbrake saved in my users application folder

So i ran the following in terminal

COMMAND : `cd /Applications shasum -a 1 HandBrake-* && shasum -a 256 HandBrake-`

and got this response which seems to be blank.. any ideas wether this is saying that i have an infected file or if ive just run the initial terminal command wrong ?

RESPONSE : `shasum: HandBrake-: Sams-MacBook-Pro:Applications Sam$ `
