NAME

SYNOPSIS

DESCRIPTION

"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 executed

-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 referenced 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, ~/.config/radare2/radare2rc and the scripts inside .../radare2rc.d/ directory.

-NN

Same as -N but also disables the automatic loading of plugins on startup time

-q

Quiet mode (no prompt) and quit after running the commands specified with -i or -c

-qq

Quit before showing the prompt. Right after all the -e -c and -i arguments are evaluated.

-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

-T

Avoid computing the file hashes

-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

-X

Same as -e bin.usextr=false, do not use extract plugins, useful for dyldcache
