Perl

We'll write more about Perl after we decipher the following code:
perl -wlne'END{print$n}eof&&$n++;/<title>([^<]+)/i&&$n--' *

Intepretation
The code in question (from the collection "The road to Perligata") is a lament over the coming apocalypse, an expression of the author's Weltschmerz and the futility of all human endeavors. Let us take it step by step:

-wlne'
-The world is near its end.

END{print$n}
-At the end the sum of all our sins and virtues will be reckoned and the judgement revealed.

eof&&$n++;
-As the evil of mankind ends, perhaps the end itself is a positive thing.

/<title>([^<]+)/
-We are preoccupied with fame and titles

i
-And insensitive to the suffering of others.

&&$n--
-All this is for nought, and only hastens our demise.

' *
-For in the end, we are but stardust.
