Add a header to a tab delimited file

Question

I\'d like to add a header to a tab-delimited file but I am not sure how to do it in one line in linux.

Let us say my file is:

Answer 1

$ { printf 'name\tage\tuniversity\tcity\n'; cat orig-file; } > new-file

Or

$ printf '1\ni\nname\tage\tuniversity\tcity\n.\nw\n' | ed -s orig-file
