SYNOPSIS
vlock [OPTIONS]
DESCRIPTION
vlock locks virtual console sessions, requiring a password to unlock. It can lock either the current console or all virtual consoles on the system.
This provides physical security for text-mode console sessions, similar to screen locking in graphical environments.

Lock all virtual consoles-h, --help

CAVEATS
Locking all consoles prevents access to any console without the password. Root can still unlock. Works only on virtual consoles, not pseudo-terminals.
