Your question is not CentOS specific.
It is not exactly clear to me what you do want to do.
info sed
sed -e '45 s/$/\n\n\n/'

For Example :

I want to modify through shell script..

elif [[ "$redhat_release" =~ "CentOS" ]]; then
[ "$BOOTUP" = "color" ] && echo -en "\\033[0;33m"
PRODUCT=`sed "s/CentOS \(.*\) release.*/\1/" /etc/centos-release`
echo -e " $PRODUCT"
[ "$BOOTUP" = "color" ] && echo -en "\\033[0;39m"

TO


elif [[ "$redhat_release" =~ "EasyDialNOW" ]]; then
[ "$BOOTUP" = "color" ] && echo -en "\\033[0;33m"
PRODUCT=`sed "s/CentOS \(.*\) release.*/\1/" /etc/centos-release`
echo -e " $PRODUCT"
[ "$BOOTUP" = "color" ] && echo -en "\\033[0;39m"

There are many answers to your question, here are just the ones i thought first:

- If you use only console and like interactivity, try vi, vim, nano or emacs
- If you use console but dislike interactivity, try sed, awk
- If you use only graphical mode, try gvim, gedit, kate, kwrite, xemacs, jedit...

Regards.

P.S: Next time try googling for "linux text editor"
