Here is the issue, I have written a ksh script that is to be run both Unix and Linux, since the script containts logic and features that only "korn" will give better/valid result, so what I want is:
whenever this program is excuted, make sure it will be running like below:
$ ksh myprog.sh
if user enter $ sh myprogram.sh
the program will prompt the use to enter "ksh myprogram.sh" instead.
Why I am asking for this, so I don't need to care wheather the default shell for a give user is a bash/csh/
What I want is logic in "myprogram.sh" to check if user does enetr the ksh before the $0 !
