Question .. Qu'est-ce que fait «2>&1» aux lignes 18 et 28?

C’est pour rediriger standard error vers standard output. Voir : http://en.wikipedia.org/wiki/Standard_streams#Standard_error_.28stderr.29

Nice! TY

Précision… c’est qu’en Ruby, les backticks (`) servent à retourner la valeur de standard output. Mais dans le script, on veut utiliser standard error, donc la façon de le retourner c’est en le redirigeant vers standard output.
