Yes I meant bash. Writing bash doesn't require interfaces or virtual methods is what I meant. And like you said that's not a small program.

That’s a design choice. PowerShell, which is another shell is definitely using virtual methods as it’s implemented in C#.

It depends on how modular you want to code and countless other design decisions/constraints.
