I'd like to know if it's possible to write a POSIX compliant script that builds a find command from it's arguments.

The way to do it for Bash (and zsh) is explained in this other SE article but it's using facilities that are Bash (or zsh) specific.

The original question was to be able to build a find command like this:

find -iname '*foo*' -o -iname '*bar*' -o -iname '*blah*'

The answer is with the following Bash script code:

findany() {
    local args=('-iname' "*$1*")
    shift

    while [ "$#" -gt 0 ]; do
        args+=('-o' '-iname' "*$1*")
        shift
    done

    find . "${args[@]}"
}

Is it possible to do something similar in a POSIX-compliant script?
