Re: File::Find in a loop

The "wanted" sub uses a GLOBAL $dir in your code. (Before I get flamed - what I mean is GLOBAL to the sub. The example below uses a lexical variable that is global to the sub)

In the "for my $dir" loop, $dir is LOCAL to the block enclosed by the "for" loop, so the "wanted" sub cannot see it.

To fix, keep $dir global:

my $dir;
for $dir (@...)...

From The Urban Dictionary: flamed being attacked online/on a forum. I think it is appropriate. Do you have an alternative suggestion ? "I'm fairly sure if they took porn off the Internet, there'd only be one website left, and it'd be called 'Bring Back the Porn!'" -- Dr. Cox, Scrubs	[reply]

flamed being attacked online/on a forum. I think it is appropriate. Do you have an alternative suggestion ? A punch in the face is an attack :) Calling someone online in a forum a you so-and-so-name-name-insult-insult for saying such-and-such is an attack, a flame. Someone saying "sorry , but that is not a global..." is not an attack, is not a flame. Even if the monks get a tad pedantic at times, turning typos into "teaching moments", this isn't a flame attack. I'm not sure, but I think you might be thinking of "nitpicking" (not nitpicking or nitpicking or pedant/pedantic) Flames aren't nice, I think PerlMonks is nice :)	[reply]


Do you know where your variables are?
