The default format describes up to 16 octets on each line, in both hexadecimal and text, with the text column in one of the following character sets:

  • --table default — a tweaked code page 437, like on an old IBM PC. This encoding provides a unique glyph for each octet, making it reversible, and almost all of those glyphs are visually distinct, which is helpful when visualising patterns in binary data that transcends printable ASCII.
  • --table classic — printable ASCII bytes shown as exactly that, and everything else as a dot, just like conventional hex-dumping tools.
  • --table reverse — printable ASCII bytes plus control pictures at 00h (␀) through 1Fh (␟) and 7Fh (␡), then the same glyphs in reverse video for 80h through FFh.

Features

  • ☑ uses pledge(2) + unveil(2) on OpenBSD
  • ☑ tweaked-437 + classic + reverse-video character sets

Requirements

  • Rust 1.46+ (tested with 1.46.0)
  • Should work on any platform including:
    • Linux
    • Windows 1511+
    • OpenBSD 6.4+

Windows notes

xd(1) currently requires ENABLE_VIRTUAL_TERMINAL_PROCESSING, which was introduced on or near Windows build 10586. This includes most versions of Windows 10 (1511+), or any version of Windows Server 2016 (1607+) or newer.

If you pipe or redirect output before it reaches the console, try --table classic for ASCII only, or set your code page to UTF-8. To enable UTF-8 on Windows version 1809 or newer, run intl.cpl, click Administrative, click Change system locale, then check Use Unicode UTF-8 for worldwide language support. If you use an older version of Windows, try one of these methods. Note that all of the methods for enabling UTF-8 have been known to cause some software in the wild to misbehave.

For best results in conhost, don’t use Raster Fonts. The other fonts offered by default work fairly well, with the exception of control pictures like ␀, because conhost doesn’t yet support font fallback. For the same reason, your mileage may vary with a custom font.
