You have to admit that this is a /bad/ script. Even if the writer
intended that behavior falling back to using ".", it would have been
better to explicitly ask for it:
$ test "$var" \
&& find "$var" \
|| find '.'
or at least document that it is using a glitch:
$ find $var # Use $var if set, else use ".".
But the latter would not work for unusual file names, of course.
Have a nice day,
