I was aware of this function from File::Spec, but misunderstood what it meant. Since it did not accept any arguments, I assumed (without testing) that it would simply return the "parent directory" of the "current working directory". Instead it returns '..'.

This means that my final solution could be simplified to: 
use File::Basename qw(dirname);
use File::Spec;

print File::Spec->rel2abs(
    File::Spec->catdir(
        dirname(__FILE__),
        File::Spec->updir(),
    )
);

However, is this right? Is this how the updir() function was intended to be used? I've probably just been ruminating on the problem for too long. But this solution still somewhat bothers me.

Also, I appreciate the RTFM reference in the spirit in which it was given. However, the acronym itself is rather rude, and often plays on false assumptions.

Thanks again,
