Synopsis

rizin[-ACdfLMnNqStuvwzX] [-P patch] [-p prj] [-a arch] [-b bits] [-i file] [-s addr] [-B baddr] [-m maddr] [-c cmd] [-e k=v] file|pid|-|--|=

Description

Rizin is a command-line reverse engineering framework designed to analyze and disassemble binary files. It provides various tools and features for analyzing and understanding the structure, behavior, and logic of executable files.

The options are:

--

Run rizin without opening any file

=

Equivalent of 'rizin malloc://512'

-

Read file from stdin

-=

Perform R=! command to run all commands remotely

-0

Print \x00 after initialization and after every command executed

-1

Redirect stderr to stdout

-2

Close stderr file descriptor (silent warning messages)

-a arch

Set the assembly architecture (x86, ppc, arm, mips, bf, java, ...)

-A

Run 'aaa' command before prompt or patch to analyze all referenced code

-b bits

Set the assembly bitness (16, 32, 64)

-B baddr

Set the base address for Position-Independent Executables (PIE)

-c 'cmd..'

Execute the specified Rizin command

-C

Specify a file in the format "host:port" to run Rizin remotely through HTTP

-d

Debug the executable 'file' or running process 'pid'

-D backend

Enable debug mode, setting the configuration variable 'cfg.debug=true'

-e k=v

Evaluate the specified configuration variable

-f

Set block size to be equal to file size

-F binplugin

Force the use of a specific rbin plugin

-h, -hh

Show help messages, with -hh showing detailed help

-H [var]

Print information about installation paths and configuration settings. This option is useful for obtaining details about the installation location, directories, and various components of Rizin.

-i file

Run the commands from the script file

-I file

Run script file before the file is loaded

-k OS/kern

Set the assembly operating system

-l lib

Load the specified plugin file

-L

List supported IO plugins

-m addr

Map file at given address

-M

Disable demangling

-n, -nn

Control loading of RzBin info, with -nn only loading binary structures

-N

Disables loading user settings from the rizinrc file (check the RZ_CONFIGHOME value in the rizin -H output).

-NN

Disable loading any scripts or plugins

-q

Quiet mode, suppresses prompt and quits after script execution

-qq

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

-p prj

Set project file

-r rz-run

Specify dbg.profile rz-run profile to use when spawning a program for debugging

-R rule

Specify custom rz-run directives without having to create a rz-run profile

-s addr

Start seeking at this address

-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 rizin library versions

-w

Open in write mode

-x

Open the file without the execute flag

-X

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

-z, -zz

Do not load strings or load them even in raw

Environment

ANSICON

W & H of the buffer and w & h of the window in the form of: "WxH (wxh)"

DEBUGINFOD_URLS

Use alternative debuginfod server via bin.dbginfo.debuginfod_urls

COLUMNS

Terminal columns to use

RZ_ABORTLEVEL

Target log level/severity when to abort (0:DEBUG, 1:VERBOSE, 2:INFO, 3:WARN, 4:ERROR, 5:FATAL)

RZ_CURL

Whether to use curl (for SSL support)

RZ_DEBUG_ASSERT

Set a breakpoint when hitting an assert

RZ_DEBUG_TOOL

Debug tool to use when showing error messages and crash signal

RZ_DYLDCACHE_FILTER

dyld cache filter (MacOS dynamic libraries location(s) at runtime)

RZ_HTTP_AUTHFILE

HTTP Authentification user file

RZ_LOGCOLORS

Should the log output use colors

RZ_LOGFILE

Logging output filename/path

RZ_LOGLEVEL

Target log level/severity (0:DEBUG, 1:VERBOSE, 2:INFO, 3:WARN, 4:ERROR, 5:FATAL)

RZ_LOGSHOWSOURCES

Should the log output contain src info (filename:lineno)

RZ_PIPE_IN

rzpipe cmd input (file descriptor)

RZ_PIPE_OUT

rzpipe cmd output (file descriptor)

RZ_PREFIX

Default prefix rizin was compiled for

RZ_RCFILE

User config file

SFLIBPATH

SFLib syscall library path

Examples

Start rizin in analysis mode (-A) on the /bin/ls executable:

rizin -A /bin/ls

Open the file /bin/ls in write mode, allowing you to make changes to the binary:

rizin -w /bin/ls

Start rizin's debugger (-d) on /bin/ls and pass arguments "-l" and "/tmp" to the program for debugging:

rizin -d /bin/ls -l /tmp
