NAME 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] [-r rarun2] [-R rr2rule] [-s addr] [-0AdDjwntLquvVxX] -|--|=|file 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 SHELL Type '?' for help VISUAL To enter visual mode use the 'V' command. Then press '?' for help DEBUGGER In r2 the debugger commands are implemented under the 'd' command. Type 'd?' for help ENVIRONMENT 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/.lo- cal/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 FILE path to the current working file.
