Die and exit command in Perl

The ‘Die’ and ‘Exit’ command in Perl is not that much same as ‘Exit’ and ‘Quit’ a program in Windows. There are some differences in their functions.  It is depended on what is needed to have happen with STDERR and STDOUT. The die command does not accept number as argument ever. It usually accepts string or nothing. It always terminates the program with error message whereas the exit command just terminates the program.mExit is used to exit the process whereas to throw an exception die is used generally. Where die always outputs a message, exit does not.

I would like to mention some other benefits/drawbacks to using die: 1) diecan be trapped with an eval, but you cannot do so I case of exit; 2) the diefunction can easily overridden.
