13 radare2 is a commandline hexadecimal editor.
14 "r2" is the alias program name for radare2.
16 This manpage is not updated yet. Feel free to contribute.
18 The options are:
20 -- Open radare2 on an empty file
22 - Equivalent of 'r2 malloc://512'
24 -0 Print \x00 after initialization and after every command exe‐
26 cuted
27 -2 Close stderr before starting RCore
29 -a arch force asm.arch (x86, ppc, arm, mips, bf, java, ...)
31 -A run 'aaa' command before prompt or patch to analyze all ref‐
33 erenced code. Use -AA to run aaaa
34 -b bits force asm.bits (16, 32, 64)
36 -B baddr Specify the base address to be used when loading a new
38 binary. See 'e?bin.baddr'
39 -c cmd Execute the given command before giving prompt
41 -d Start in debugger mode
43 -D dbg.backend
45 Enable debug mode. Set cfg.debug=true
46 -e k=v Set configuration eval variable key=value. For example -e
48 scr.color=false
49 -f Blocksize = file size
51 -i file Run script file. After the file is loaded
53 -I file Run script file. Before the file is loaded
55 -k kernel Select kernel (asm.os) for syscall resolution
57 -l plugfile
59 Load given plugin file
60 -L List supported IO plugins.
62 -m addr map file at given address
64 -M Disable demangling
66 -n Do not perform any analysis (r_bin). Just load the raw file
68 -nn Only load the rbin structures (elf, mach0, ...)
70 -N Do not load user settings/projects from ~/.radare2rc, ~/.con‐
72 fig/radare2/radare2rc and the scripts inside .../radare2rc.d/
73 directory.
74 -q Quiet mode (no prompt) and quit after running the commands
76 specified with -i or -c
77 -qq Quit before showing the prompt. Right after all the -e -c and
79 -i arguments are evaluated.
80 -Q Same as q, but exiting without freeing RCore, this produces
82 leaks at exit time, but saves some precious ms to run the
83 testsuite in fast mode.
84 -p prj Set project file
86 -P file Apply rapatch file and quit (see doc/rapatch.md for more
88 details)
89 -r rarun2 Specify dbg.profile rarun2 profile to use when spawning a
91 program for debugging
92 -R rarun2-directive
94 Specify custom rarun2 directives without having to create a
95 rarun2 profile
96 -s addr Start seeking at this address
98 -S Enable sandboxed mode (same as -e cfg.sandbox=true)
100 -t Get binary information using a thread
102 -T Avoid computing the file hashes
104 -u Set bin.filter=false to load rbin info without filtering
106 names
107 -v Show version information and exit (Use -qv to get just the
109 version number)
110 -V Show radare2 library versions
112 -w Open in write mode
114 -h Show help message
116 -H Show files and environment help
118 -x Open the file map without executable permissions
120 -X Same as -e bin.usextr=false, do not use extract plugins, use‐
122 ful for dyldcache
123
125 Type '?' for help
126
128 To enter visual mode use the 'V' command. Then press '?' for help
129
131 In r2 the debugger commands are implemented under the 'd' command. Type
132 'd?' for help
133
135 RHOMEDIR ~/.config/radare2
136 RCFILE ~/.radare2rc (user preferences, batch script)
137 R2_MAGICPATH /usr/lib/radare2/0.10.0-git/magic
138 R_DEBUG if defined, show error messages and crash signal
139 VAPIDIR path to extra vapi directory FILE path to the current work‐
140 ing file.
