Linux+ Cert Practice Question


Quote:
You want to run an interactive script, gabby, which produces a lot of output in response to the user's inputs. To facilitate future study of this script, you want to copy its output to a file. How might you do this?

gabby > gabby-out.txt

gabby | tee gabby-out.txt

gabby < gabby-out.txt

gabby &> gabby-out.txt
I don't have an interactive script that I know of, so i decided to use gpg --gen-key because it's interactive. The last command captured the stderr, but not the stdout.
