frrffr4
grtgt
gthth

dddrr

here I want country to be replaced. First occurence of countryshould be my_country and rest of the occurences with our_country as:

aaa
bbb
ccccc
my_country
dddd
our_country
frrffr4
grtgt
gthth

Try this:

awk 'BEGIN {r="my_country"} /country/ {print r; r="our_country"; next} {print}'
