In Bash, can I output text from cut into a new command? This might be a vague title, but it's hard to explain what I'm doing in a short title. 

I have a tool that removes adware and it mainly runs in bash. Some of the programs I want to kill may have multiple PIDs or output files. Here's what I have and what I want to do:

lsof +D /Applications/appIDontWant.app/ | cut -d " " -f 2 1&gt;


So I have this which gets the PIDs for the application and I can then output using 1> to a text or something, but what if I want to output the PIDs to a 

sudo kill 


? Would this be another time to use | ? (I'm vaguely familiar with pipe, but not great.)

Now, I do know that I can simply put 

sudo kill appIDontWant.app 


but that's just not any fun.
Assuming your command results in a number of PIDs

sudo kill $(lsof +D /Applications/appIDontWant.app/ | cut -d " " -f 2)


should do the trick.
