Test for file
I have a script that performs certains functions is a file exists in the specified directory:
if [ -s $DATA_DIR/test.das ]
then
How can you do the reverse of this, basically an "if file does not exist"?

test::data
Data(3pm) User Contributed Perl Documentation Data(3pm)
NAME
Test::Data -- test functions for particular variable types
SYNOPSIS
use Test::Data qw(Scalar Array Hash Function);
DESCRIPTION
Test::Data provides utility functions to check properties and values of data and variables.
Functions
Plug-in modules define functions for each data type. See the appropriate module.
How it works
The Test::Data module simply imports functions from Test::Data::* modules. Each module defines a self-contained function, and puts that
function name into @EXPORT. Test::Data defines its own import function, but that does not matter to the plug-in modules.
If you want to write a plug-in module, follow the example of one that already exists. Name the module Test::Data::Foo, where you replace
Foo with the right name. Test::Data should automatically find it.
BUGS
I'm not a very good Windows Perler, so some things don't work as they should on Windows. I recently got a Windows box so I can test things,
but if you run into problems, I can use all the patches or advice you care to send.
