I am making a script. i need to automate a portion that looks at all the files in the directory containing the string "HNAZXLCOM" in the name then take the newest file with that string in the name and put the filename into a variable.

function latest {
    if [[ $FUNCNAME == ${FUNCNAME[1]} ]]; then
        unset -v x latest files
        printf -v "$@"
    elif (($# > 2)); then
        printf '%s\n' "Usage: $FUNCNAME <glob> <varname>" 'Error: Takes at most 2 arguments. Glob defaults to *'
        return 1
    else
        if ! shopt -q nullglob; then
            typeset -f +t "$FUNCNAME"
            trap 'shopt -u nullglob; trap - RETURN' RETURN
            shopt -s nullglob
        fi

        IFS= typeset -a 'files=(${1:-*})'
        typeset latest x

        for x in "${files[@]}"; do
            [[ -d $x || $x -ot $latest ]] || latest=$x
        done

        ${2:+"$FUNCNAME"} "${2:-printf}" -- %s "$latest"
    fi
}


latest '*HNAZXLCOM*' myVar
