fgconsole - print the number of the active VT.
fgconsole [ -h --help | -V --version | -n --next-available ]
If 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. -h --help Prints short usage message and exits. -V --version Prints version number and exits. --next-available 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.
Under devfs, the consoles are in /dev/vc/N. devfsd may maintain symlinks for compatibility.
