Huh? Could someone explain this? The "}{" makes no sense to me...
Well, as Momma used to say: "Just look the other way. Ignore it, and maybe it will go away..."
I would not be at all surprised if the code above works, and does *something*. I just prefer to use code that says what it is doing.
The idea with '}{' is brilliant in my opinion. See the "-p" switch explaination in perldoc perlrun:
http://www.perldoc.com/perl5.8.0/pod/perlrun.html#-p
and substitute the "..." with }{*_=*.}{ to see how it works. Hint: it's the same as:
perl -lpe '}{$_=$.}{'
As for the code that says what it is doing, here it is:
perl -le 'while(<>){} print $.'
Do nothing for every line of input and print the number of lines, just like "wc -l" would.
