[SOLVED] xrdb - remove a single resource entry

Is there a way to remove a single resource entry from resource databse?

-remove This option indicates that the specified properties  should  be
               removed from the server.

I tried following commands, but all three nuke the whole database.

xrdb -remove .Xresources

xrdb -remove "URxvt.perl-ext-common"

xrdb -remove

I believe that is impossible. You can do a query/sed/load cycle, though.

Re: [SOLVED] xrdb - remove a single resource entry

A cursory review of the source shows that "-remove" is intended to delete the entire database, and documentation is wrong.  (Note final four lines.)

if (doScreen) {
xdefs = XScreenResourceString (ScreenOfDisplay(dpy, scrno));
root = RootWindow(dpy, scrno);
res_prop = XInternAtom(dpy, SCREEN_RESOURCES, False);
} else {
xdefs = XResourceManagerString (dpy);
root = RootWindow(dpy, 0);
res_prop = XA_RESOURCE_MANAGER;
}
if (oper == OPSYMBOLS) {
printf ("%s\n", defines.val);
} else if (oper == OPQUERY) {
if (xdefs)
	printf ("%s", xdefs);	/* fputs broken in SunOS 4.0 */
} else if (oper == OPREMOVE) {
if (xdefs)
	XDeleteProperty(dpy, root, res_prop);
}

Re: [SOLVED] xrdb - remove a single resource entry

Thanks for your responses and even looking through the source code
I shall mark this "solved", although the problem is unsolvable without a workaround.
