The Official Radare2 Book

Radiff2

Radiff2 is a tool designed to compare binary files, similar to how regular diff compares text files.

$ radiff2 -h

Usage: radiff2 [-abBcCdjrspOxuUvV] [-A[A]] [-g sym] [-m graph_mode][-t %] [file] [file]

-a [arch] specify architecture plugin to use (x86, arm, ..)

-A [-A] run aaa or aaaa after loading each binary (see -C)

-b [bits] specify register size for arch (16 (thumb), 32, 64, ..)

-B output in binary diff (GDIFF)

-c count of changes

-C graphdiff code (columns: off-A, match-ratio, off-B) (see -A)

-d use delta diffing

-D show disasm instead of hexpairs

-e [k=v] set eval config var value for all RCore instances

-g [sym|off1,off2] graph diff of given symbol, or between two offsets

-G [cmd] run an r2 command on every RCore instance created

-i diff imports of target files (see -u, -U and -z)

-j output in json format

-n print bare addresses only (diff.bare=1)

-m [aditsjJ] choose the graph output mode

-O code diffing with opcode bytes only

-p use physical addressing (io.va=0)

-q quiet mode (disable colors, reduce output)

-r output in radare commands

-s compute edit distance (no substitution, Eugene W. Myers' O(ND) diff algorithm)

-ss compute Levenshtein edit distance (substitution is allowed, O(N^2))

-S [name] sort code diff (name, namelen, addr, size, type, dist) (only for -C or -g)

-t [0-100] set threshold for code diff (default is 70%)

-x show two column hexdump diffing

-X show two column hexII diffing

-u unified output (---+++)

-U unified output using system 'diff'

-v show version information

-V be verbose (current only for -s)

-z diff on extracted strings

-Z diff code comparing zignatures

Graph Output formats: (-m [mode])
