require ‘zlib’

Dir.chdir("/home/prove")  
puts Dir.pwd  
IO.foreach(“ordinati”) do |file|  
f = Zlib::GzipReader.open(file)  
end

il file ordinati esiste e lo trova, tanto e’ vero che se faccio “puts  
file”  
mi da il suo contanuto.  
In ogni riga di “ordinati” ci sono nomi di files .gz che si trovano  
sempre  
all’interno della directory /home/prove e che voglio aprire uno per uno.  
Tuttavia la f = Zlib::GzipReader.open(file) mi dice che il file non  
esiste.  
Ma perche’?

prova ad eliminare il carattere \n dal nome dei file con

f = Zlib::GzipReader.open(file.chomp)
