Did you mean:
my $size = -s $_;
Perl already has all the info from the previous lstat command, using _
is more efficient in that it doesn't have to do another system call.
That is very interesting, actually. What piece of documentation should I
read to learn about this operators?
I am not sure how to bring it up using the perldoc, I read it when I
was going through the book "Learning Perl". Maybe someone else here
can point out how to find it in perldoc..
perldoc -f -X
