Question Add key column to the row
I have source like this with tab delimited
Code:
Jon	Newyork	7024051234	jon@email.com
eric	Newjersy	5021236541	eric@email.com
johnson	Baltimore	9142013210	john@email.com

I want to add key column to each row
Code:
1	Jon	Newyork	7024051234	jon@email.com
2	eric	Newjersy	5021236541	eric@email.com
3	johnson	Baltimore	9142013210	john@email.com

Since volume of the data is too high, I need to do it OS level not in DB level.

Suggest me awk or sed command to insert identity for each row.

Thanks,
EM
