Vrms è un’utilità per sistemi GNU/Linux basati su Debian che analizza i pacchetti installati sul nostro computer e ci informa su quali di questi non hanno una licenza libera (non-free software).

Si installa con un semplicissimo:

# aptitude install vrms

E si lancia con:

$ vrms

Ecco il mio risultato:

mirko@mirko:~$ vrms
