Assuming that the path of the file to investigate is stored on variable file, the naive approach to test, whether it is a candidate for deletion, would be (in, say, bash or zsh)
Alternatively, you could also write in this particular case
or
The problem is how you want to treat files which have some content, but no terminating newline, and files which are completely empty. For them, *wc -l* would report zero. Depending on whether or not you want to delete them too, you would have to adapt the condition accordingly.

xkbaddgeomoverlaykey
XkbAddGeomOverlayKey(3) XKB FUNCTIONS XkbAddGeomOverlayKey(3)NAME
XkbAddGeomOverlayKey - Add a key to an existing overlay row
SYNOPSIS
XkbOverlayKeyPtr XkbAddGeomOverlayKey (XkbOverlayPtr overlay, XkbRowPtr row, char *under);
ARGUMENTS
- overlay
overlay to be updated
- row row in overlay to be updated
- under
primary name of the key to be considered
DESCRIPTION
Xkb provides functions to add a single new element to the top-level keyboard geometry. In each case the num_ * fields of the corresponding
structure is incremented by 1. These functions do not change sz_* unless there is no more room in the array. Some of these functions fill
in the values of the element's structure from the arguments. For other functions, you must explicitly write code to fill the structure's
elements.
The top-level geometry description includes a list of geometry properties. A geometry property associates an arbitrary string with an
equally arbitrary name. Programs that display images of keyboards can use geometry properties as hints, but they are not interpreted by
Xkb. No other geometry structures refer to geometry properties.
XkbAddGeomOverlayKey adds one key to the row in the overlay. If there is no key named under in the row of the underlying section, XkbAd-
dGeomOverlayKey returns NULL.
STRUCTURES
typedef struct _XkbOverlayKey {
XkbKeyNameRec over; /* name of this overlay key */
XkbKeyNameRec under; /* name of the key under this overlay key */
} XkbOverlayKeyRec,*XkbOverlayKeyPtr;
