openssl command line to verify the signature

Hi I have generated a key pair and used the private key to generate a signature.

openssl rsautl -sign -in helloworld.txt -inkey aa.pem -out sig

However I am unable to verify the signature with my public key:

openssl rsautl -verify -in helloworld.txt -inkey aa.pub -sigfile sig

I know there -sigfile is deprecated. and some of the online doc from openssl.org is wrong.

Whats the command I should use to verify the sig with my public key?
