Hexadecimal diff viewer for Linux

Question

I am looking for a good hexadecimal viewer for Linux.

It should have a GUI and be intuitive to use.

It should also be able to compare two files and maybe even show a diff.

Answer 1

Hex diff viewers with console/terminal graphics:

• vbindiff, Divides screen into top and bottom, no right/left view, fixed-width output.
• hexdiff, Same top/bottom look as vbindiff, fixed-width output, and it can be a hex editor.
• dhex Top/bottom diff viewer, hex editor, resizable-width output, (fits terminal), and offers better navigation.

Graphical hex diff viewers: I don't know of one, but here's a shell function using mgdiff, (which has left/right view), and hexdump (AKA hd), inefficiently:

mgdiffhex () 
{ 
    a="/tmp/$(basename "$1")$$.hex"
    b="/tmp/$(basename "$2")$$.hex"
    hd "$1" > "$a"
    hd "$2" > "$b"
    mgdiff "$a" "$b"
    rm     "$a" "$b"
}

Then run:

mgdiffhex foo bar

Notes: The hexdump util can be invoked with formatting options that allow for arbitrary terminal widths; mgdiffhex can be resized but lacks any means of reformatting the hex dumps within the resized window. Combining them makes for a crude graphical hex diff viewer.
