SYNOPSIS
radare2 [-a arch] [-b bits] [-B baddr] [-c cmd] [-e k=v] [-i 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'
-0 Print \x00 after initialization and after every command exe‐
cuted
-2 Close stderr before starting RCore
-a arch force asm.arch (x86, ppc, arm, mips, bf, java, ...)
-A run 'aaa' command before prompt or patch to analyze all ref‐
erenced code. Use -AA to run aaaa
-b bits force asm.bits (16, 32, 64)
-B baddr Specify the base address to be used when loading a new
binary. See 'e?bin.baddr'
-c cmd Execute the given command before giving prompt
-d Start in debugger mode
-D dbg.backend
Enable debug mode. Set cfg.debug=true
-e k=v Set configuration eval variable key=value. For example -e
scr.color=false
-f Blocksize = file size
-i file Run script file. After the file is loaded
-I file Run script file. Before the file is loaded
-k kernel Select kernel (asm.os) for syscall resolution
-l plugfile
Load given plugin file
-L List supported IO plugins.
-m addr map file at given address
-M Disable demangling
-n Do not perform any analysis (r_bin). Just load the raw file
-nn Only load the rbin structures (elf, mach0, ...)
-N Do not load user settings/projects from ~/.radare2rc, ~/.con‐
fig/radare2/radare2rc and the scripts inside .../radare2rc.d/
directory.
-q Quiet mode (no prompt) and quit after running the commands
specified with -i or -c
-Q 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.
-p prj Set project file
-P file Apply rapatch file and quit (see doc/rapatch.md for more
details)
-r rarun2 Specify dbg.profile rarun2 profile to use when spawning a
program for debugging
-R rarun2-directive
Specify custom rarun2 directives without having to create a
rarun2 profile
-s addr Start seeking at this address
-S Enable sandboxed mode (same as -e cfg.sandbox=true)
-t Get binary information using a thread
-u Set bin.filter=false to load rbin info without filtering
names
-v Show version information and exit (Use -qv to get just the
version number)
-V Show radare2 library versions
-w Open in write mode
-h Show help message
-H Show files and environment help
-x Open the file map without executable permissions
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)
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 work‐
ing file.
