can anyone tell which shell should be used to write script?
korn or bash?

Honestly, that is up to your personal preference overall, but I recommend using bash. I use zsh for my shell, and bash when it comes to shell scripting.

On linux systems bash is used most often, but using ksh is possible. I would use bash, but in the end it is up to you.
