This should work with any arbitrary filename:

    latest=$(printf '%s\0' <glob> | sort -zrV | head -zn1)

or with long args:

    latest=$(printf '%s\0' <glob> | sort --zero-terminated --reverse --version-sort | head --zero-terminated --lines 1

What unix is this on? Neither the mac nor gnu manpages have a -z or --zero-terminated option for head.

Debian's head (from GNU coreutils) does: https://manpages.debian.org/bookworm/coreutils/head.1.en.htm...
