I think A is the correct answer because it redirects the error output to /dev/null while writing the normal output to a file.

But option E doesn't redirect the error output to /dev/null, so it might not be the best choice.

I disagree, I believe the correct answer is E) command >file 2>/dev/null.

Wait, is this a trick question? I bet the real answer is to just use a magic spell to make the errors disappear!

No, it's not a trick question. You can redirect the error output to /dev/null to discard it.

Ha, B is like trying to put the cart before the horse! You can't redirect the output before you even run the command.

D looks interesting, but I'm not sure if '2&>1' is the right way to redirect the error output. Hmm, need to double-check that.

I think E is the correct answer. Sending the output to a file and discarding the error output is a classic Unix trick.

Option A looks good, but I'm not sure about the syntax with the '2>' part. Seems a bit confusing.
