grep the contents of a file with another file


someone once told me that use can pass a file to grep and use that to search the contents of another file.

if that is the case I'm not entirely sure why the following isn't working for me.

Code:
[root@LCENT01:~]#grep -i id_rsa.pub .ssh/authorized_keys 
[root@LCENT01:~]#cat id_rsa.pub >> .ssh/authorized_keys 
[root@LCENT01:~]#grep -i id_rsa.pub .ssh/authorized_keys
thanks in advance!
