rz-diff - Man Page

unified binary diffing utility


rz-diff[-AabcCdDhOrspxXvzZ] [-t 0-100] [-g sym] [-S algo] file1 file2


rz-diff implements many binary diffing algorithms for data and code.


Analyze binary after loading it with RzCore (see -C) and use -AA to run aaaa instead of aaa.


Specify architecture (x86, arm, ..)


Select register size bits for given arch


Binary output (GDIFF format)


Count number of differences.


Code diffing using graphdiff algorithm. Output columns are: file-a-address, percentage of most similar function in B file | file-b-address. (Use with -A to analyze the binaries to find more functions)


Use delta diffing (slower).


Show disasm instead of hexpairs (honors -a arch and -b bits)

-e -[k=v]

Specify eval config vars for all RzCore instances created.

-g sym | off1,off2

Graph diff output of given symbol, or between two functions, at given offsets: one for each binary.

-G -[cmd]

Run an rz command on every RzCore instance created


Show usage help message.


Compare the list of imports

-m -[mode]

Specify the graph output mode


Suppress address names (show only addresses) when code diffing.


Do code diffing with opcode bytes only.


Use physical addressing (io.va=0)


Quiet mode: disable colors and reduce output


Output in rizin commands as a binary patch.


Show two column hexdump diffing.


Show two column hexII diffing.


Compute edit distance (no substitution, Eugene W. Myers' O(ND) diff algorithm) between two files.


Compute Levenshtein edit distance (substitution is allowed, O(N^2)) between two files.

-S [name, namelen, dist, size, ...]

Specify which column of the code diffing algo use for diffing

-t 0-100

Choose matching threshold for binary code diffing


Unified diff output


Unified diff output using system´s diff program


Show version information.


Be verbose sometimes


Perform diff on extracted strings


Perform diff using zignatures instead of function list (NEW)
