Advanced commandline hexadecimal editor, disassembler and debugger

SYNOPSIS

radare2 [-a arch] [-b bits] [-B baddr] [-c cmd] [-e k=v] [-i file] [-I prefile] [-k kernel] [-m addr] [-p project] [-P patch] [-r rarun2] [-R rr2rule] [-s addr] [-0AdDwntLquvVxX] -|--|=|file

DESCRIPTION

radare2 is a commandline hexadecimal editor.

"r2" is the alias program name for radare2.

This manpage is not updated yet. Feel free to contribute.

The options are:

--
Open radare2 on an empty file
-
Equivalent of 'r2 malloc://512'
Print \x00 after initialization and after every command executed
Close stderr before starting RCore
arch
force asm.arch (x86, ppc, arm, mips, bf, java, ...)
run 'aaa' command before prompt or patch to analyze all referenced code. Use -AA to run aaaa
bits
force asm.bits (16, 32, 64)
baddr
Specify the base address to be used when loading a new binary. See 'e?bin.baddr'
cmd
Execute the given command before giving prompt
Start in debugger mode
dbg.backend
Enable debug mode. Set cfg.debug=true
k=v
Set configuration eval variable key=value. For example -e scr.color=false
Blocksize = file size
file
Run script file. After the file is loaded
file
Run script file. Before the file is loaded
kernel
Select kernel (asm.os) for syscall resolution
plugfile
Load given plugin file
List supported IO plugins.
addr
map file at given address
Disable demangling
Do not perform any analysis (r_bin). Just load the raw file
Only load the rbin structures (elf, mach0, ...)
Do not load user settings/projects from ~/.radare2rc, ~/.config/radare2/radare2rc and the scripts inside .../radare2rc.d/ directory.
Quiet mode (no prompt) and quit after running the commands specified with -i or -c
Quit before showing the prompt. Right after all the -e -c and -i arguments are evaluated.
Same as q, but exiting without freeing RCore, this produces leaks at exit time, but saves some precious ms to run the testsuite in fast mode.
prj
Set project file
file
Apply rapatch file and quit (see doc/rapatch.md for more details)
rarun2
Specify dbg.profile rarun2 profile to use when spawning a program for debugging
rarun2-directive
Specify custom rarun2 directives without having to create a rarun2 profile
addr
Start seeking at this address
Enable sandboxed mode (same as -e cfg.sandbox=true)
Get binary information using a thread
Avoid computing the file hashes
Set bin.filter=false to load rbin info without filtering names
Show version information and exit (Use -qv to get just the version number)
Show radare2 library versions
Open in write mode
Show help message
Show files and environment help
Open the file map without executable permissions
Same as -e bin.usextr=false, do not use extract plugins, useful for dyldcache

SHELL

Type '?' for help

VISUAL

To enter visual mode use the 'V' command. Then press '?' for help

DEBUGGER

In r2 the debugger commands are implemented under the 'd' command. Type 'd?' for help

ENVIRONMENT


RHOMEDIR ~/.config/radare2
RCFILE ~/.radare2rc (user preferences, batch script)
R2_MAGICPATH /usr/lib/radare2/0.10.0-git/magic
R_DEBUG if defined, show error messages and crash signal
VAPIDIR path to extra vapi directory FILE path to the current working file.
