NAME
rabin2 - Binary Information Extractor

SYNOPSIS
rabin2 [-AcdeEghHiIjJlLMpqQrRsStuUVvwxZ] [-a arch] [-b bits] [-B addr] [-C fmt:C:[D]] [-D lang sym|-] [-f subbin] [-F binfmt] [-k query] [-K algo] [-m addr] [-n str] [-N minlen:maxlen] [-o str] [-O binop] [-X fmt file ...] [-@ addr] file

DESCRIPTION
A binary information extractor supporting ELF, PE, MZ, and Mach-O formats, providing details on headers, sections, symbols, imports, exports, and debug data.

Most options are also available within the radare2 'i' command (type 'i?' for help).

-@ addr
    Show section, symbol or import at given address

-A  List sub-binaries and their associated arch-bits pairs

-a arch
    Set arch (x86, arm, .. or <arch>_<bits>)

-b bits
    Set bits (32, 64, ...)

-B addr
    Override base address (for address independent binaries)

-c  List classes

-cc List classes in header format

-C [fmt:C[:D]]
    Create [elf,mach0,pe] with Code and Data hexpairs (see -a)

-d  Show debug/dwarf information

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

-e  Program entrypoint

-ee Constructor/destructor entrypoints

-E  Globally exportable symbols

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

-F binfmt
    Force to use that bin plugin (ignore header check)

-g  Same as -SMZIHVResizcld -SS -SSS -ee (show all info)

-G addr
    Load address . address to header

-h  Show this help message

-H  Header fields

-I  Binary info

-i  Imports (symbols imported from libraries)

-j  Output in json

-J var
    Display environment variable

-k query
    Perform SDB query on loaded file. For example: '*'

-K algo
    Calculate section checksums (md5, sha1, ..)

-l  List linked libraries to the binary

-L plugin
    List supported bin plugins or plugin details

-m addr
    Show source line at addr

-M  Main (show address of main symbol)

-n str
    Show section, symbol or import named str

-N minlen:maxlen
    Force min:max number of chars per string (see -z and -zz)

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

-O binop
    Perform binary operation on target binary (dump, resize, change sections, ...). Use -O help for more information:

         e/0x8048000       change entrypoint
         d/s/1024          dump symbols
         d/S/.text         dump section
         r/.data/1024      resize section
         R                 remove RPATH
         a/l/libfoo.dylib  add library
         p/.data/rwx       change section permissions
         c                 show Codesign data
         C                 show LDID entitlements

-p  Show always physical addresses

-P  Show debug/pdb information

-PP Download pdb file for binary

-q  Be quiet, just show less data

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

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

-r  Radare output

-R  Relocations

-s  Symbols

-S  Sections

-SS Segments

-SSS
    Sections mapping to segments

-t  Display file hashes

-T  Display file signature, certificates and signing details

-u  Unfiltered (no rename duplicated symbols/sections)

-U  Resources

-v  Display version and quit

-V  Show binary version information

-w  Display try/catch blocks

-x  Extract sub-binaries contained in file (for example inside FAT mach-o binaries)

-X format file ...
    Package in fat or zip the given files

-z  Strings (from data section)

-Z  Guess size of binary program

-zz Show strings from raw bins

-zzz
    Dump raw strings to stdout (for huge files)

ENVIRONMENT

R2_NOPLUGINS
    Same as r2 -N. Do not load shared plugins

RABIN2_ARGS
    Ignore CLI and use these arguments instead

RABIN2_CHARSET
    Set default value charset for -z strings

RABIN2_CODESIGN_VERBOSE
    Show codesign details at parse time

RABIN2_DEBASE64
    Same as r2 -e bin.str.debase64 - try to decode all strings as base64 if possible

RABIN2_DEMANGLE
    Same as r2 -e bin.demangle - demangle symbols

RABIN2_DEMANGLE_CMD
    Same as r2 -e bin.demangle.cmd - try to purge false positives

RABIN2_DEMANGLE_TRYLIB
    Same as r2 -e bin.demangle.trylib=<bool> - load Swift libs to demangle (default: false)

RABIN2_LANG
    Same as r2 -e bin.lang - assume lang for demangling

RABIN2_MACHO_NOFUNCSTARTS
    If set it will ignore the FUNCSTART information
