Re^2: hash count

I usually use "scalar keys %hash" to find how many pairs are in a %hash.

scalar grep defined($_) values %hash

I think that should be:

scalar grep defined, values %hash;
[download]

scalar grep { defined } values %hash;
[download]

`scalar grep defined($_) values %hash`I think that should be: ... It could be as you have written it, but I think moritz may have been considering the relative inexperience of the OPer by passing the parameter explicitly rather than implicitly. Also, the code fragment was `scalar grep defined($_), values %hash` (comma present after the `defined($_)` built-in call) in moritz's original reply (unless moritz has been updating replies without noting the fact – unlikely!).

(unless moritz has been updating replies without noting the fact – unlikely!). I did, mea culpa. (I sometimes do that when the node is still very new and there are no replies and it's a small change. But if it causes confusion, I try to clarify it).	[reply]

Yes, I forgot the comma after the `defined`, and updated my post. Thanks to ikegami for noting it.	[reply] [d/l]
