View Full Version : quick shell scripting question

April 5th, 2009, 10:36 PM
i read in one of my books that a shellscript should be for security reasons ended whit an -
like example
#! /bin/bash - and i want to know if it is right and if so how about when you write python or perl scripts. should they be written as
#! /usr/bin/perl - or in python
#! /usr/bin/env python - the book i refere to is classical shell scripting .
its a book from o.reily publising.

thanks for any information on the subject.

no, you would only do that for bash. it just logs you in differently, for more info check man bash

i just wondered since i know you can pass options to perl like #! usr/bin/perl -w
so it could be that you also had to do that for other kinds of shellscript languages but i never seen or heard of it before today when i started reading this book.
