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’

Print � after initialization and after every command executed

Close stderr before starting RCore

force asm.arch (x86, ppc, arm, mips, bf, java, …)

run ‘aaa’ command before prompt or patch to analyze all referenced code. Use -AA to run aaaa

force asm.bits (16, 32, 64)

Specify the base address to be used when loading a new binary. See ’e?bin.baddr’

Execute the given command before giving prompt

Start in debugger mode

Enable debug mode. Set cfg.debug=true

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.

Blocksize = file size

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.

Run script file. After the file is loaded

Run script file. Before the file is loaded

Select kernel (asm.os) for syscall resolution

Load given plugin file

List loaded IO plugins.

List loaded core plugins.

map file at given address

Disable demangling

Do not perform any analysis (r_bin). Just load the raw file

Only load the rbin structures (elf, mach0, …)

Do not load user settings/projects from ~/.radare2rc, ~/.config/radare2/radare2rc and the scripts inside …/radare2rc.d/ directory.

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

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

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

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.

Set project file

Apply rapatch file and quit (see doc/rapatch.md for more details)

Specify dbg.profile rarun2 profile to use when spawning a program for debugging

Specify custom rarun2 directives without having to create a rarun2 profile

Start seeking at this address

Enable sandboxed mode (same as -e cfg.sandbox=true)

Get binary information and analyze binary in a background thread

Avoid computing the file hashes

Set bin.filter=false to load rbin info without filtering names

Show version information and exit (Use -qv to get just the version number)

Show radare2 library versions (prints JSON format if -j is used)

Open in write mode

Show help message

Show files and environment help

Open the file map without executable permissions

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

Type ‘?’ for help

To enter visual mode use the ‘V’ command. Then press ‘?’ for help

In r2 the debugger commands are implemented under the ’d’ command. Type ’d?’ for help

R2_ARGS run radare2 with defined arguments in environment and ignore cli ones R2_IGNVER load plugins ignoring the specified version. (be careful) R2_DEBUG if defined, show error messages and crash signal R2_DEBUG_ASSERT=1 set a breakpoint when hitting an assert R2_MAGICPATH /Users/pancake/.local/share/radare2/share/radare2/4.5.0-git/magic R2_NOPLUGINS do not load r2 shared plugins R2_RCFILE ~/.radare2rc (user preferences, batch script) R2_RDATAHOME /usr/local

path to the current working file.
