RZ-DIFF(1)

💖 RZ_DIFF — like, the manual page for rz-diff (that's the RZ-DIFF(1) page bestie, section 1) 💖

okay so picture this: you got two files. two binaries. two whole vibes. and you need to know what's different between them. that's it. that's the whole thing. rz-diff is your girl for this. let's go 🦋

✨ SYNOPSIS ✨

rz-diff [OPTIONS] file0 file1

---

🌸 DESCRIPTION 🌸

so rz-diff takes two files or binary programs, compares them, and highlights the differences between them. like a glow-up reveal but for bytes. 💅

and it's not just raw bytes either — it can diff a bunch of different aspects, depending on which options you pass: raw bytes, text lines, functions, sections, strings, etc. etc. pick your fighter.

🎀 the options, bestie 🎀

• -A — compare virtual addresses from file0 with physical addresses in file1
• -a [arch] — tell it which architecture plugin to use for analysis (think x86, arm)
• -b [bits] — set the register size for whichever architecture you picked (think 16, 32, 64)
• -B — run 'aaa' when loading the binary
• -C — disable colors in the output (no fun allowed mode, but valid)
• -d [algo] — compute the edit distance between the files with the algorithm you pick:
  • myers — Eugene W. Myers' O(ND) algorithm (no substitution)
  • leven — Levenshtein O(N^2) algorithm (with substitution)
  • ssdeep — Context triggered piecewise hashing comparison
• -e [k=v] — set an evaluable config variable
• -H — turn on hexadecimal visual mode so you can compare files in hex format 👀
• -h — display the help message
• -i — use command line arguments instead of files (only for -d)
• -j — output the comparison results in JSON format
• -q — generate quiet output with minimal information
• -0 [cmd] — input for file0 when option -t 'commands' is given
• -1 [cmd] — input for file1 when option -t 'commands' is given
• -S [WxH] — set the width and height of the terminal for visual mode
• -t [type] — compute the difference between two files based on the type you pick:
  • bytes — compare raw bytes in the files (only for small files, fr)
  • lines — compare text files
  • functions — compare functions found in the files
  • classes — compare classes found in the files
  • command — compare command output returned when executed in both files. Requires -0 <cmd>, -1 <cmd> is optional.
  • entries — compare entries found in the files
  • fields — compare fields found in the files
  • graphs — compare 2 functions and outputs in graphviz/dot format. Requires -0 <fcnname|offset>, -1 <fcn name|offset> is optional.
  • imports — compare imports found in the files
  • libraries — compare libraries found in the files
  • sections — compare sections found in the files
  • strings — compare strings found in the files
  • symbols — compare symbols found in the files
• -T — show timestamp information in the output
• -V — show version information for rz-diff
• -v — be more verbose (stderr output)

palette check!! 🌈 you can change the palette colors by adding the following lines inside the $HOME/.rizinrc file:

ec diff.unknown blue
        offset color

ec diff.match green
        match color

ec diff.unmatch red
        mismatch color

⭐ EXAMPLE ⭐

compare two binary files using the default settings:

rz-diff file1.bin file2.bin

compare two text files and display the output in JSON format:

rz-diff -j -t lines file1.txt file2.txt

compare two functions from an architecture plugin:

rz-diff -t graphs -0 function1 -1 function2 binary1 binary2
