One Day One GNU/Linux Command
=============================
deallocvt -- Deallocate Unused Virtual Consoles.
Summary:
The command deallocvt deallocates kernel memory and data structures
for all *UNUSED* virtual consoles.
When you do 'openvt', a new virtual console will be created on the
next free terminal. After using that, We can deallocate it using the
'deallocvt' command.
Examples:
# openvt -s ls -- Run the 'ls' on next free VT (mostly on tty7).
# deallocvt -- Deallocate unused VT. Now switch to tty7, you won't
see any change on the screen.
# deallocvt 7 -- Deallocate /dev/tty7, if it is unused.
Read: man deallocvt
