When I installed Oracle 8.1.6 on Red Hat Linux 6.2 a lot of scripts in $ORACLE_HOME/bin/ didn't work.

Today I figured out that they are written for Kornshell (#!/bin/ksh), and I had to change them.

I don't use Kornshell and I don't even have it installed on my machine.

The the question is: Is Kornshell a requirement for ORACLE?
