    Its certainly not a scheme I'd use, but I've also seen Makefile and

    The GNU “make” command, specified without a filename, looks for “GNUmakefile”, then “Makefile”, then “makefile”. The man page <https://manpages.debian.org/make(1)> says:

    We recommend Makefile because it appears prominently near the
    beginning of a directory listing, right near other important files
    such as README.

    But is this still true for most people? I think the default sort
    settings these days no longer put all-caps names at the top.

    On Linux, try:

    LC_COLLATE=C ls -l

    ...and the capitalized filenames will float to the top.

    Does it work on linux as well as on the Panix machines?

    Yes.

    Here's what's up. When I run locale(1) on Linux Mint, I see:

    [...]
    LC_COLLATE="en_US.UTF-8"
    [...]

    So ordering is case-insensitive, apparently:

    $ ls -l
    total 28
    -rwxrwxr-x 1 vallor vallor 16016 Jan 10 2024 ckarray
    -rw-rw-r-- 1 vallor vallor 169 Jan 10 2024 ckarray.c
    -rw-rw-r-- 1 vallor vallor 24 May 1 19:59 Makefile
    -rw-rw-r-- 1 vallor vallor 63 Jan 10 2024 phrase.txt

    But setting it to "C", I get:

    $ LC_COLLATE=C ls -l
    total 28
    -rw-rw-r-- 1 vallor vallor 24 May 1 19:59 Makefile
    -rwxrwxr-x 1 vallor vallor 16016 Jan 10 2024 ckarray
    -rw-rw-r-- 1 vallor vallor 169 Jan 10 2024 ckarray.c
    -rw-rw-r-- 1 vallor vallor 63 Jan 10 2024 phrase.txt

    ...which is the case-sensitive sort order.

    A Panix convention.

    Does it work on linux as well as on the Panix machines?

    The glibc Linux boxen work with that. 'LC_COLLATE=C' seems to mean
    "tradional C behavior". I'm not sure how non-glibc Linux behaves
    (thinking of Alpine). I suspect those don't even need the variable.
