Vim (Vi IMproved) è un famoso editor di testo che può essere utilizzato per editare testo di ogni genere: tipicamente si utilizza per il codice C/C++, PHP, Python, Perl ed altri ancora. In ambiente SSH può essere utile per modificare i file di configurazione del vostro VPS, fermo restando che esistono editor più semplici da sfruttare (come ad esempio pico): in questo nuovo articolo andremo a vedere come si possa installare Vim.
Anzitutto andiamo a fare login sul nostro VPS (o server dedicato, a seconda dei casi) in questo modo:
ssh nomeu@IP
Ci verrà richiesta la password dell’utente nome, la inseriamo e dopo qualche istante dovremmo avere accesso alla macchina remota. Andiamo ora ad installare, da console remota e dopo aver fatto correttamente login, il file del programma con il seguente comando:
apt-get install vim
L’output generato sarà il seguente:

In caso abbiate invece già installato il software comparirà invece una notifica del genere (e non sarà necessario fare nulla, la cosa è da considerarsi normale):
Reading package lists... Done Building dependency tree Reading state information... Done vim is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and ... not upgraded.
A questo punto possiamo editare i nostri file con Vim, ad esempio:
vim nomefile.php
Attenzione: prima di utilizzare il programma è bene familiarizzare con la sua interfaccia (vedi guida).
