Hi,

To do something like this you just have to edit the file, not sure what editor you'll have but you can use Vi, Vim, Emacs, Gedit or any number of editors to do that.

Regards

Dave

If you want to add the same Mer.out.host6 "fun5.tp" read everytime with first value different, you can use below
Code:
awk 'NF > 1 {p=$1; print; next} NR > 1{print p, "Mer.out.host6 \"fun5.tp\" read"}1' FS=. OFS=. /tmp/a.txt
