# radiff(1)

Unified binary diffing utility

## NAME

**radiff** – Unified binary diffing utility

## SYNOPSIS

**radiff** \[-cbgeirp\] \[-f \[from\]\] \[-t \[to\]\] \[file.a\] \[file.b\]

## DESCRIPTION

radiff implements some binary diffing algorithms.

- **-b**

  Use bytediff (byte-per-byte binary diffing between two target files), this is the faster way to do it, but it will not handle byte insertion or offset displacements.

- **-c**

  Show output in disassembly format with delta offset support.

- **-d**

  Use the GNU diff as backend (slow, but really good output)

- **-e**

  Use the erg0ts generic c++ implementation of bindiff.

- **-n**

  Display only the number of differences found.

- **-r**

  Display results as radare commands (used to generate binary patch files)

- **-s**

  Use rsc symdiff to find differences at symbol level (support delta diffing)

- **-S**

  Use rsc symbytediff to find differences at symbol level using a byte-per-byte binary comparision algorithm.

- **-p**

  Perform a diff between two RDB files (radare databases) these files can be generated from radare using the code analysis commands, or from IDA using the ida2rdb.idc script)

- **-f** **-\[from\]**

  Define from address (start looking for differences at offset 'from'

- **-t** **-\[to\]**

  Define end address (stop binary diffing at offset 'to'

- **-h**

  Show usage help message.

## NOTES

Check 'man rsc-bindiff'
