I have a file which look like this:
A3 124.406526 8.281803
A3' 125.000684 8.389677
K4 123.072842 8.166373
K4' 120.092553 8.269080
I want to add characters in the 1st column, and the file will should be like:
A3N-H 124.406526 8.281803
A3'N-H 125.000684 8.389677
K4N-H 123.072842 8.166373
K4'N-H 120.092553 8.269080
How can I do this in a easy way by awk or sed?
