How can I get the original language of the text?

I know I can use -id and that is showing the Name, Family, Writing system, Code etc but I need only the Code from this list.

trans -id  "how are you today?" -no-auto

So if I write the above thing in shell I get this list and I want only know the Code (en):

Name English

Family Indo-European

Writing system Latin

Code en

ISO 639-3 eng

SIL https://iso639-3.sil.org/code/eng

$ trans -id  "how are you today?" -no-auto | grep Code | awk '{print $2}'
