You may like to know GNU's uniq(1) has ‘-D’ to print all duplicates
and ‘-i’ to ignore case.

    $ find -type f | sort -f | uniq -Di
    ./man2/_exit.2
    ./man2/_Exit.2
    ./man3/nan.3
    ./man3/NAN.3
    ./man3/sd_bus_error_map.3
    ./man3/SD_BUS_ERROR_MAP.3
    ./man8/pam.8
    ./man8/PAM.8
    $

GNU's grep(1) has ‘-m’ for the maximum number of matches.

    $ grep -m1 ^ `find -type f | sort -f | uniq -Di`
