Hi GhostDog,

Thanks for your explanation. But still it seems abstract to me.

Can i say that this statement " FNR==NR&&/^\*\*/{line=$2;next} " will only operate on the 1st input file since the rest of the code is un-true for the 1st input file ?

As for the next part of the code starting with " FNR!=NR&&$0~line .... " , it will only operate on the 2nd input file ?

Am i understanding it correctly ?

But what would be the value of FNR and NR values when operating on the 1st input file ?
And what would be the value of FNR and NR values when operating on the 2nd input file ?
