SYNOPSIS

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

DESCRIPTION

This program allows you to get information about ELF/PE/MZ and CLASS files in a simple way. All those commandline flags are also available under the i command in radare2. Type i? for help. -@ addr Show information (symbol, section, import) of the given ad‐ dress -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 (iI in r2) -i Show imports (symbols imported from libraries) (ii) -j Output in json -k query Perform SDB query on loaded file -K algo Select a rahash2 checksum algorithm to be performed on sec‐ tions 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. Show physical addresses -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 -u Unfiltered (no rename duplicated symbols/sections) -v Show version information -V Show binary version information -x Extract all sub binaries from a fat binary (f.ex: 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_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.strfilter for rabin2 RABIN2_STRPURGE same as r2 -e bin.strpurge for rabin2

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
