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.
