RADIFF2(1) BSD General Commands Manual RADIFF2(1)NAME
RADIFF2 — unified binary diffing utility
SYNOPSISradiff2 [-AabcCdDhOrspxvz] [-t 0-100] [-g sym] [-S algo] file1 file2
DESCRIPTIONradiff2 implements many binary diffing algorithms for data and code.
-A Analyze binary after loading it with RCore (see -C) and use
-AA to run aaaa instead of aaa.
-a Specify architecture (x86, arm, ..)
-b Select register size bits for given arch
-c Count number of differences.
-e -[k=v] Specify eval config vars for all RCore instances created.
-C 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)
-d Use delta diffing (slower).
-D Show disasm instead of hexpairs (honors -a arch and -b bits)
-g sym | off1,off2
Graph diff output of given symbol, or between two functions,
at given offsets: one for each binary.
-h Show usage help message.
-i Compare the list of imports
-n Suppress address names (show only addresses) when code diff‐
ing.
-O Do code diffing with all bytes instead of just the fixed
opcode bytes
-p Use physical addressing (io.va=0)
-q Quiet mode: disable colors and reduce output
-r Output in radare commands as a binary patch.
-x Show two column hexdump diffing.
-s Calculate text distance from two files.
-ss Same as before but using the Levenstein algorithm (faster but
sometimes buggy)
-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
-u Unified diff output
-U Unified diff output using system´s diff program
-v Show version information.
-V Be verbose sometimes
-z Perform diff on extracted strings
