"Why 'eval' this..."
Good question. Because:
Perhaps all items match ;-)
My posts aren't correct: it would only make (some) sense to eval if there is a die in the block that sets $@ (perhaps something wrong with $command, like a non-existing file etc). But this could be also trapped before with a file test operator...a.s.o
I just wanted to say that you forgot to right shift, as you already noticed. That would have been enough. Sorry :-(
To tell the truth: from time to time i need to take a look again at Perl documentation about this issues. I think it can be tricky - depending on the situation. And even if it isn't really tricky, i get a little confused about it from time to time...
Best regards, Karl
