Re^3: Is there a better way to check if an array is empty?

You are using next, and have an outcommented last, without a loop. You also have an if followed by a block.

I can't make sense of what you are doing, let alone suggest a better way. I do know that many people prefer to use a consistent indenting, but for some reason, many people asking the questions on Perlmonks seem to prefer some random indentation. (But I've seen worse).

To say in short again,I am searching for a new file in the keys of a hash and pushing the grep results to an array,if the array is emtpy then only push the new file to another array "@newfiles" and then come out of the loop(that's the reason I added a next)	[reply]

Your code has no loop! Maybe you need to show a little more of the code? It would be even better to mock up some data and show the result you expect compared with the result you are getting - at present it's not clear because your code doesn't match your comments. True laziness is hard work	[reply]

and then come out of the loop One way of improving your code is to create a loop. Without a loop, you can't come out of it.	[reply]
