chvt

Change to a specific TTY

$ sudo chvt [3]

chvt N

chvt changes the foreground virtual terminal to terminal N. Virtual terminals (VTs) are the text consoles accessible via Ctrl+Alt+F1 through F7 on most Linux systems.
This is equivalent to pressing Ctrl+Alt+FN but can be done programmatically or when keyboard shortcuts are unavailable.

N

The virtual terminal number to switch to (typically 1-7)

Requires root privileges. The target VT must exist. On systems with graphical desktop, VT7 or VT1 is typically the X/Wayland session. Available VTs depend on system configuration.
