Salve a tutti,

come posso gestire l’uscita dall’esecuzione di uno script via “control  
^C”?  
Vorrei che una volta premuto “^C” lo script esca in maniera pulita senza  
riportare warning a video.

Grazie

p.s. se nella form di “Search” di questo sito cerco “^C”, mi ritorna un  
codice 500 (errore a livello server se non sbaglio). Sarebbe il caso di  
segnalarlo?

hai provato con:

Signal.trap(“INT”) do  
Process.exit  
end

Niente da fare. Ottengo cmq diverse righe “…`close’: stream closed  
(IOError)…” ☹

se da un errore ci sarà un motivo, sarebbe meglio al posto di  
sopprimere il messaggio di errore, intercettare il segnale, chiudere  
tutti gli stream,file,socket e altro che deve essere chiuso e solo ora  
chiamare exit!(0)

magari usando:

Signal.trap(“INT”) do  
Process.exit!(0)  
end
