also - ‘which’, being too Debian-specific, will not return the filespec if its file permission is too restrictive. - ‘command -v’, also will not display binary if its file permission is too restrictive. - ‘whereis -b’ works just fine as long as /usr/sbin has world RX file mode or other lesser matching filemods. Still stuck on ‘whereis’
