NAME

rabin2 — Binary program info extractor

SYNOPSIS

DESCRIPTION

This program allows you to get information about ELF/PE/MZ and CLASS files in a simple way.

All those command-line flags are also available under the i command in radare2. Type i? for help.

-@ addr

Show information (symbol, section, import) of the given address

-A

List sub-binaries and their associated arch-bits pairs

-a arch

Set arch (x86, arm, .. accepts underscore for bits x86_32)

-b bits

Set bits (32, 64, ...)

-B addr

Override baddr

-c

List classes

-cc

List classes in header format

-C [fmt:C[:D]]

Create [elf,mach0,pe] for arm and x86-32/64 tiny binaries where 'C' is an hexpair list of the code bytes and ':D' is an optional concatenation to describe the bytes for the data section.

-d

Show debug/dwarf information

-D lang symbolname|-

Demangle symbol name (or - to read from stdin) for lang (cxx, swift, java, cxx, ..)

-e

Show entrypoints for disk and on-memory

-ee

Show constructor/destructors (extended entrypoints)

-f subbin

Select sub-binary architecture. Useful for fat-mach0 binaries

-F binfmt

Force to use that bin plugin (ignore header check)

-g

Show all possible information

-G addr

Load address . offset to header

-h

Show usage help message.

-H

Show header fields (see ih command in r2)

-I

Show binary info (see iI command in r2)

-i

Show imports (symbols imported from libraries) (see ii command in r2)

-j

Output in json

-k query

Perform SDB query on loaded file

-K algo

Select a rahash2 checksum algorithm to be performed on sections listing (and maybe others in the future) i.e 'rabin2 -K md5 -S /bin/ls'

-l

List linked libraries to the binary

-L

List supported bin plugins

-M

Show address of 'main' symbol

-m addr

Show source line reference from a given address

-N minlen:maxlen

Force minimum and maximum number of chars per string (see -z and -zz). if (strlen>minlen && (!maxlen || strlen<=maxlen))

-n str

Show information (symbol, section, import) at string offset

-o str

Output file/folder for write operations (out by default)

-O binop

Perform binary operation on target binary (dump, resize, change sections, ...) see '-O help' for more information

-p

Disable VA. Always show physical addresses (not the same as -B0)

-P

Show debug/pdb information

-PP

Download pdb file for binary

-q

Be quiet, just show fewer data

-qq

Show less info (no offset/size for -z for ex.)

-Q

Show load address used by dlopen (non-aslr libs)

-r

Show output in radare format

-R

Show relocations

-s

Show exported symbols

-S

Show sections

-SS

Show segments

-t

Show file hashes

-T

Show certificates

-u

Unfiltered (no rename duplicated symbols/sections)

-U

Show resources

-v

Show version information

-V

Show binary version information

-w

Show try/catch blocks

-x

Extract all sub binaries from a fat binary (for example: fatmach0)

-X format file ...

Package a fat or zip containing all the files passed (fat, zip)

-z

Show strings inside .data section (like gnu strings does)

-Z

Guess size of binary program

-zz

Shows strings from raw bins

-zzz

Dump raw strings to stdout (for huge files)

ENVIRONMENT

RABIN2_ARGS ignore cli and use these arguments instead

RABIN2_LANG same as r2 -e bin.lang for rabin2

RABIN2_DEMANGLE demangle symbols

RABIN2_MAXSTRBUF same as r2 -e bin.maxstrbuf for rabin2

RABIN2_DEBASE64 try to decode all strings as base64 if possible

RABIN2_STRFILTER same as r2 -e bin.str.filter for rabin2

RABIN2_STRPURGE same as r2 -e bin.str.purge for rabin2

RABIN2_DEMANGLE_TRYLIB same as r2 -e bin.demangle.trylib=<bool> - try to dynamically load libraries to demangle

RABIN2_VERBOSE same as r2 -e bin.verbose=true

EXAMPLES

List symbols of a program

$ rabin2 -s a.out

Get offset of symbol

$ rabin2 -n _main a.out

Get entrypoint

$ rabin2 -e a.out

Load symbols and imports from radare2

$ r2 -n /bin/ls
[0x00000000]> .!rabin2 -prsi $FILE
