Execute the above, then call part of your scheme to assign each of the elements to your array. Personally, I would avoid dash if possible if you need features like typedef, declare, arrays.... AFAIK a Linux system with /bin/sh == dash also will have /bin/bash available, too. ---Not applicable to ARM linux and other minimized CE versions of Linux. A shebang with #!/bin/bash seems preferable. Unless of course this is all just meant for fun. You do realize that extensive workarounds for production systems are generally bad idea.

regulatory.bin(5)                                                      Linux                                                     regulatory.bin(5)

NAME

       regulatory.bin, regulatory.db - The Linux wireless regulatory database

Description
       regulatory.bin and regulatory.db are the files used by the Linux wireless subsystem to keep its regulatory database information.

       regulatory.bin is read by crda upon the Linux kernel's request for regulatory information for a specific ISO / IEC 3166 alpha2 country
       code.

       regulatory.db is a newer, extensible database format which (since Linux 4.15) is read by the kernel directly as a firmware file.

       The regulatory database is kept in a small binary format for size and code efficiency. The regulatory.bin file can be parsed and read in
       human format by using the regdbdump command. The regulatory database files should be updated upon regulatory changes or corrections.

Upkeeping
       The regulatory database is maintained by the community as such you are encouraged to send any corrections or updates to the linux-wireless
       and wireless-regdb mailing lists: linux-wireless@vger.kernel.org and wireless-regdb@lists.infradead.org
