The radare core accepts many flags from the command line.
This is an excerpt from the usage help message: ``` $ radare2 -h Usage: r2 [-ACdfLMnNqStuvwzX] [-P patch] [-p prj] [-a arch] [-b bits] [-i file] [-s addr] [-B baddr] [-m maddr] [-c cmd] [-e k=v] file|pid|-|--|= -- run radare2 without opening any file - same as 'r2 malloc://512' = read file from stdin (use -i and -c to run cmds) -= perform !=! command to run all commands remotely -0 print \x00 after init and every command -2 close stderr file descriptor (silent warning messages) -a [arch] set asm.arch -A run 'aaa' command to analyze all referenced code -b [bits] set asm.bits -B [baddr] set base address for PIE binaries -c 'cmd..' execute radare command -C file is host:port (alias for -c+=http://%s/cmd/) -d debug the executable 'file' or running process 'pid' -D [backend] enable debug mode (e cfg.debug=true) -e k=v evaluate config var -f block size = file size -F [binplug] force to use that rbin plugin -h, -hh show help message, -hh for long -H ([var]) display variable -i [file] run script file -I [file] run script file before the file is opened -k [OS/kern] set asm.os (linux, macos, w32, netbsd, ...) -l [lib] load plugin file -L list supported IO plugins ``` ``` -m [addr] map file at given address (loadaddr) -M do not demangle symbol names -n, -nn do not load RBin info (-nn only load bin structures) -N do not load user settings and scripts -q quiet mode (no prompt) and quit after -i -Q quiet mode (no prompt) and quit faster (quickLeak=true) -p [prj] use project, list if no arg, load if no file -P [file] apply rapatch file and quit -r [rarun2] specify rarun2 profile to load (same as -e dbg.profile=X) -R [rr2rule] specify custom rarun2 directive -s [addr] initial seek -S start r2 in sandbox mode -t load rabin2 info in thread -u set bin.filter=false to get raw sym/sec/cls names -v, -V show radare2 version (-V show lib versions) -w open file in write mode -x open without exec-flag (asm.emu will not work), See io.exec -X same as -e bin.usextr=false (useful for dyldcache) -z, -zz do not load strings or load them even in raw ```
Open a file in write mode without parsing the file format headers.
$ r2 -nw file
Quickly get into an r2 shell without opening any file.
$ r2 -
Specify which sub-binary you want to select when opening a fatbin file: ``` $ r2 -a ppc -b 32 ls.fat ``` Run a script before showing interactive command-line prompt:
$ r2 -i patch.r2 target.bin
Execute a command and quit without entering the interactive mode: ``` $ r2 -qc ij hi.bin > imports.json ``` Set the configuration variable:
$ r2 -e scr.color=0 blah.bin
Debug a program: ``` $ r2 -d ls ``` Use an existing project file:
$ r2 -p test
