    Hmm. I definitely recall otherwise.

    The old Unix definition is that the empty string stands for "."
    so that 'ls ""' means the same as 'ls .'
    and 'ls /tmp/""' the same as 'ls /tmp/.'.

    Let me try.

    On a recent Linux system:

    % ls -l ""
    ls: cannot access : No such file or directory

    On an old Unix system:

    # ls -l ""
    drwxr-xr-x 2 bin 1040 Jan 1 1970 bin
    drwxr-xr-x 2 bin 352 Jan 1 1970 dev
    drwxr-xr-x 2 bin 304 Aug 20 12:39 etc
    ...

    Andries
