Do you mean that if vishakapatnam comes after the 8th line? Then you can use this

Code:

awk ' NR > 8 && /VISAKHSAPATNAM/,/good/ { sub("^#","")};1 ' filename

after visakhapatnam the next 8 lines should un comment

not as visakhapatnam to good

from viskahaptnam to next 8 lines

Code:

awk ' /VISAKHSAPATNAM/ {n=8;next} n{ sub("^#","");n--}1' filename

Why do not y use sed. I think sed is easy to do so.

sed 's/#//'

If you want to uncomment the lines from 'XXX' to 8 line, you can use this:

sed '/XXX/,8 s/#//'

use AWK you can follow this:

awk '{/sub(/#/,"",$0)}'
