Btrieve Dump

Reads a Btrieve data file and prints every record, in the order found in the file. Each line of output corresponds to one record in space-delimited, hexadecimal format.

Usage

Let's say we have a Btrieve file called valar.dat with 15 records measuring 22 bytes each matching the following structure:

struct Valar {
    uint8_t id;
    uint8_t name[20];
    uint8_t spouse_id;
};

$ btrieve-dump valar.dat

If you need it in binary format, you could use something like xxd:

$ btrieve-dump valar.dat | xxd -revert -plain > valar.bin
$ xxd -cols 22 -groupsize 1 valar.bin
