Polecenie grpconv

Wykonanie, użycie: System administration command. Like pwconv, the grpconv command creates a shadowed group file to keep your encrypted group passwords safe from password-cracking programs. grpconv creates the /etc/gshadow file based on your existing /etc/groups file and replaces your encrypted password entries with x. If you add new entries to the /etc/groups file, you can run grpconv again to transfer the new information to /etc/gshadow. It will ignore entries that already have a password of x and convert those that do not. grpunconv restores the encrypted passwords to your /etc/groups file and removes the /etc/gshadow file
