NAMEfgconsole - print the number of the active VT.
DESCRIPTIONIf the active Virtual Terminal is /dev/ttyN, then prints N on standard output.
If the console is a serial console, then "serial" is printed instead.
Will show the next unallocated virtual terminal. Normally 6 virtual
terminals are allocated, with number 7 used for X; this will return
"8" in this case.
