I need to insert a blank line after two lines in a file that I did with

cat rat hat
pot NOT lot
big big big
sit sit sit
awk 'print;(NR%2==0)print ""'
cat rat hat
pot NOT lot

big big big
sit sit sit

Actually my main target is to insert a new word after every two lines and I can't solve.

How can I do as I have <= 6000 names in another file in column three and even in this column few have just .(dot) in it.

Second I don't want the blank line after last line.

This seems perfect, to insert fixed WORD every two lines

awk 'print
 (NR%2==0)printf "WORDn"'

not to insert on last line, i would suggest

awk 'NR>2 && (NR%2==1) printf "WORDn"
 print ; ' 

number of column in line doesn't matter.

However, just guessing, it is not a fixed word ? a word from the line ? the last one ?

awk 'NR>2 && (NR%2==1) printf "%sn",last
 print ; last=$NF ; ' 

this will print, the last word every other line.

Replace $NF by $3 to get the third.

Creating a program is not only code, but being able to describe to others (and oneself) what is to be achieved.
