Hi Ravi, The first line "#!...." tells the program how te read the executable. F.e. if you would change it into "#!/bin/ksh" it means your (perl) script will be executed using ksh. Therefor you will get errors from the korn-shell as it's a different language.
The meaning of this is that whenever users have f.e a born-shell (in the passwd-file) and you have written a korn-shell scipt you can explicitly always use a korn-shell to execute the program. So in that case you can also tell him to use a different version of perl, just lead him to the correct location. Hope this clarifies the meaning of the first line for you.
