Re: [linux_var] zsh: reload history

OK, grazie per la puntualizzazione.

Il 5 marzo abbiamo una mezzora d'amicizia su zsh tenuta da Buccia.
Se cercate sul wiki del linuxvar trovate pure alcuni file di
configurazioni della zsh fatti da Buccia.

Io la uso perché mi trovo meglio. Ha un autocompletamento più furbo, ad esempio.
L'ho vista usare, l'ho provata e mi è piaciuta.

In gentoo la shell di default è bash.


Ciao
Lorenzo
