Windows batch equivalent of hexdump -ve '1/1 "%.2x"'

Question

I need to get the hexa value of a file i have.

On linux, this was Simply done with :

hexdump -ve '1/1 "%.2x"' Filename

However, on Windows, i couldn't found a good equivalent for hexdump. I'm using MinGW64, so basically i was looking for a hexdump.exe that i could simply add to my MinGW repo. I did found two of them, but none is the same as the linux one; they're just the same as hexdump -C

So, do you know a good equivalent, or a way to get what i want with others functions? (but no PowerShell function). I got sed and awk if that could help...

Here is an example; if i have this file named TEST:

TEST:

test test test

then i want to have this result:

746573742074657374207465737420

(without any newline)

NOTE I take absolutely no credit for this. I am only posting this as reference to future questions.

@Dbenham created a great script for this over at Dostips

usage information can be found by running hexdump /h

example usage: hex_dump.cmd /I TEST.txt /O output /NL /NA /NO

:::HEXDUMP [/Option [Value]]...
:::
:::  Writes the content of stdin as hexadecimal to stdout, with 16 bytes per line,
:::  using the following format:
:::
:::    OOOOOOO XX XX XX XX XX XX XX XX  XX XX XX XX XX XX XX XX   AAAAAAAAAAAAAAAA
:::
:::  where:
:::
:::    0000000          = the hexadecimal offset within the input
:::    XX               = the hexadecimal value of a byte
:::    AAAAAAAAAAAAAAAA = the bytes as ASCII (control codes and non-ASCII as .)
:::
:::  Output is encoded as ASCII, with each line terminated by CarriageReturn
:::  LineFeed.
:::
:::  The behavior can be modified by appending any combination of the following
:::  options:
:::
:::    /I InFile  - Input from InFile instead of stdin
:::    /O OutFile - Output to OutFile instead of stdout: - overwrites InFile
:::    /NA - No ASCII
:::    /NO - No Offsets
:::    /R  - Raw hexadecimal on a single line, with no space between bytes
:::    /LF - LineFeed as line terminator instead of CarriageReturn LineFeed
:::    /NL - No Line terminators, all output on one line without line terminator
:::    /U  - Unicode encoded output with BOM (UTF-16)
:::    /V  - Write version info to stdout
:::    /?  - Write this help to stdout
