perl -lpe '}{*_=*.}{' file
Ooh, an obfuscated verbose way of writing:
perl -lpe'}{$_=$.' file
Huh? Could someone explain this? The "}{" makes no sense to me...
I thought the same thing, when I read it! I'm still not sure I get it, but perlrun say the -p switch expands to:
LINE:
while (<>) {
... # your program goes here
} continue {
print or die "-p destination: $!\n";
}If your string is literally dropped in there, it might end the while loop and then start another block.
Just a guess.
