hi
buddies

i want to write a awk script

for the file like this:

Aaj rootha huwa ek dost bahut yaad aaya,
Achha guzra huwa kuch waqt bahut yaad aaya,
Meri aankhon ke har ek ashq pe rone wala,
Aaj jab aankh yeh royi to bahut yaad aaya,
Jo mere dard ko seene mein chhupa leta thaa,
Jo meri aankh mein kajal ki tarah rehta thaa,
Aaj kajal jo lagaya to bahut yaad aaya,
Jo mere dil ke thaa kareeb faqat uss ko hi,
Aaj jab dil ne bulaya to bahut yaad aaya.

so using this file i want to insert a new line , after this line Jo mere dard ko seene mein chhupa leta thaa

the outfile should be like this:
Aaj rootha huwa ek dost bahut yaad aaya,
Achha guzra huwa kuch waqt bahut yaad aaya,
Meri aankhon ke har ek ashq pe rone wala,
Aaj jab aankh yeh royi to bahut yaad aaya,
Jo mere dard ko seene mein chhupa leta thaa,
this is narayana , how r u sos and so
Jo meri aankh mein kajal ki tarah rehta thaa,
Aaj kajal jo lagaya to bahut yaad aaya,
Jo mere dil ke thaa kareeb faqat uss ko hi,
Aaj jab dil ne bulaya to bahut yaad aaya.

regards
narayana

I don't get what you are trying to do here, but here's an easy way to do it:

echo "Aaj rootha huwa ek dost bahut yaad aaya,
Achha guzra huwa kuch waqt bahut yaad aaya,
Meri aankhon ke har ek ashq pe rone wala,
Aaj jab aankh yeh royi to bahut yaad aaya,
Jo mere dard ko seene mein chhupa leta thaa,
Jo meri aankh mein kajal ki tarah rehta thaa,
Aaj kajal jo lagaya to bahut yaad aaya,
Jo mere dil ke thaa kareeb faqat uss ko hi,
Aaj jab dil ne bulaya to bahut yaad aaya." | awk '{if($0~/Jo mere dard ko seene mein chhupa leta thaa,/) print  $0,"\n","this is narayana , how r u sos and so"; else print $0}'
Aaj rootha huwa ek dost bahut yaad aaya,
Achha guzra huwa kuch waqt bahut yaad aaya,
Meri aankhon ke har ek ashq pe rone wala,
Aaj jab aankh yeh royi to bahut yaad aaya,
Jo mere dard ko seene mein chhupa leta thaa,
 this is narayana , how r u sos and so
Jo meri aankh mein kajal ki tarah rehta thaa,
Aaj kajal jo lagaya to bahut yaad aaya,
Jo mere dil ke thaa kareeb faqat uss ko hi,
Aaj jab dil ne bulaya to bahut yaad aaya.

There will be better ways, though.
