.Sh DESCRIPTION
|
|
radiff2 implements many binary diffing algorithms for data and code.
|
|
.Pp
|
|
.Bl -tag -width Fl
|
|
.It Fl 1
|
|
Binary output (GDIFF format)
|
|
.It Fl A
|
|
Analyze binary after loading it with RCore (see -C) and use -AA to run aaaa instead of aaa.
|
|
.It Fl a
|
|
Specify architecture (x86, arm, ..)
|
|
.It Fl b
|
|
Select register size bits for given arch
|
|
.It Fl B Ar baddr
|
|
Specify the base address to add to the offsets in the diff listings
|
|
.It Fl c
|
|
Count number of differences.
|
|
.It Fl e [k=v]
|
|
Specify eval config vars for all RCore instances created.
|
|
.It Fl 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)
|
|
.It Fl d
|
|
Use delta diffing (slower).
|
|
.It Fl D
|
|
Show disasm instead of hexpairs (honors -a arch and -b bits)
|
|
.It Fl g Ar sym | off1,off2
|
|
Graph diff output of given symbol, or between two functions, at given offsets: one for each binary.
|
|
.It Fl h
|
|
Show usage help message.
|
|
.It Fl i Ar i, s
|
|
Compare imports or symbols from given files (radiff2 -ii /bin/ls /bin/cat)
|
|
.It Fl n
|
|
Suppress address names (show only addresses) when code diffing.
|
|
.It Fl O
|
|
Do code diffing with opcode bytes only.
|
|
.It Fl p
|
|
Use physical addressing (io.va=0)
|
|
.It Fl q
|
|
Quiet mode: disable colors and reduce output
|
|
.It Fl r
|
|
Output in radare commands as a binary patch.
|
|
.It Fl x
|
|
Show two column hexdump diffing.
|
|
.It Fl X
|
|
Show two column hexII diffing.
|
|
.It Fl s
|
|
Compute edit distance (no substitution, Eugene W. Myers' O(ND) diff algorithm) between two files.
|
|
.It Fl ss
|
|
Compute Levenshtein edit distance (substitution is allowed, O(N^2)) between two files.
|
|
.It Fl S Ar [name, namelen, dist, size, ...]
|
|
Specify which column of the code diffing algo use for diffing
|
|
.It Fl t Ar 0\-100
|
|
Choose matching threshold for binary code diffing
|
|
.It Fl u
|
|
Unified diff output
|
|
.It Fl U
|
|
Unified diff output using system\'s diff program
|
|
.It Fl v
|
|
Show version information.
|
|
.It Fl V
|
|
Be verbose sometimes
|
|
.It Fl z
|
|
Perform diff on extracted strings
|
|
.It Fl Z
|
|
Perform diff using zignatures instead of function list (NEW)
