The options are:
|
|
.Bl -tag -width Fl
|
|
.It Fl Fl
|
|
Open radare2 on an empty file
|
|
.It Fl
|
|
Equivalent of 'r2 malloc://512'
|
|
.It Fl 0
|
|
Print \\x00 after initialization and after every command executed
|
|
.It Fl 2
|
|
Close stderr before starting RCore
|
|
.It Fl a Ar arch
|
|
force asm.arch (x86, ppc, arm, mips, bf, java, ...)
|
|
.It Fl A
|
|
run 'aaa' command before prompt or patch to analyze all referenced code. Use -AA to run aaaa
|
|
.It Fl b Ar bits
|
|
force asm.bits (16, 32, 64)
|
|
.It Fl B Ar baddr
|
|
Specify the base address to be used when loading a new binary. See 'e?bin.baddr'
|
|
.It Fl c Ar cmd
|
|
Execute the given command before giving prompt
|
|
.It Fl d
|
|
Start in debugger mode
|
|
.It Fl D Ar dbg.backend
|
|
Enable debug mode. Set cfg.debug=true
|
|
.It Fl e Ar 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.
|
|
.It Fl f
|
|
Blocksize = file size
|
|
.It Fl 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.
|
|
.It Fl i Ar file
|
|
Run script file. After the file is loaded
|
|
.It Fl I Ar file
|
|
Run script file. Before the file is loaded
|
|
.It Fl k Ar kernel
|
|
Select kernel (asm.os) for syscall resolution
|
|
.It Fl l Ar plugfile
|
|
Load given plugin file
|
|
.It Fl L
|
|
List loaded IO plugins.
|
|
.It Fl LL
|
|
List loaded core plugins.
|
|
.It Fl m Ar addr
|
|
map file at given address
|
|
.It Fl M
|
|
Disable demangling
|
|
.It Fl n
|
|
Do not perform any analysis (r_bin). Just load the raw file
|
|
.It Fl nn
|
|
Only load the rbin structures (elf, mach0, ...)
|
|
.It Fl N
|
|
Do not load user settings/projects from ~/.radare2rc, ~/.config/radare2/radare2rc and the scripts inside .../radare2rc.d/ directory.
|
|
.It Fl NN
|
|
Same as -N but also disables the automatic loading of plugins on startup time
|
|
.It Fl q
|
|
Quiet mode (no prompt) and quit after running the commands specified with -i or -c
|
|
.It Fl qq
|
|
Quit before showing the prompt. Right after all the -e -c and -i arguments are evaluated.
|
|
.It Fl 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.
|
|
.It Fl p Ar prj
|
|
Set project file
|
|
.It Fl P Ar file
|
|
Apply rapatch file and quit (see doc/rapatch.md for more details)

|
|
.It Fl T

Avoid computing the file hashes
|
|
.It Fl u
|
|
Set bin.filter=false to load rbin info without filtering names
|
|
.It Fl v
|
|
