       radare2	--  Advanced command-line 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]

DESCRIPTION
       radare2 is a command-line 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 ex-
		   ecuted

       -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  bi-
		   nary. 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. When -e is passed after -j,	 it  will  set
		   the script source to	run instead of setting eval vars.

       -f	   Blocksize = file size

       -j	   Run	QJS  script  if	an argument is passed or enter the qjs
		   shell if no file is specified. You can evaluate expressions
		   when	passing	the -e flag after the -j.

       -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	loaded IO plugins.

       -LL	   List	loaded core 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 plug-
		   ins 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 and	analyze	binary in a background
		   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 (prints JSON format if	-j  is
		   used)

       -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
