Perl - what run level
Is there a way to tell what runlevel is currently being used,

for example is a user is using the gui

or is the have pressed Alt+Ctrl+F1 to drop to the terminal??

who -r usually gives the run-level.

But I have no idea what Perl or a GUI or a convoluted keyboard shortcut has to do with it Smilie

Your grammar precludes me understanding your actual requirement.

Check the DISPLAY environment variable. If it is empty or unset the user is not using the X GUI environment used by most Linux distros.

Also check for the EDITOR environment variable. If this is set it is the user's preferred editor.
