How to Spit out warnings on uninitialized variables in Perl?

rajeshkumar replied the topic: Re: Spit out warnings on uninitialized variables Perl

#!/usr/local/bin/perl -w

This will help you (really, it will force you) to write better, cleaner code. Adding the -w switch to the perl interpreter will cause it to spit out warnings on uninitialized variables – potential bugs.
