Using IF statement with Grep to determine ethernet status

I'm trying to create code to determine the status of my ethernet connection. For that I'm trying to capture the output of the command:

route get cnn.com | grep interface

..in code. The output from the CLI is "interface: en0". (depending on if you're wired or wireless)

My (non working code) segment: if [[ route get cnn.com | grep grep interface | head -2 | tail -1 | awk {'print$2'} | cut -f1 -d: -eq "interface: en0" ]]

Output: grep: interface: No such file or directory
