    Here is a great tip to find the r2 command you are looking for: Execeute "?*~<keyword>" where "keyword" is a word describing the thing you are looking for. It can be "imports", "shellcode", "qword" and anything else. Same goes for "e??~<keyword>" for config variables.

    By pressing the 'e' key in panels mode you can edit the command to run on any panel. Type 'axt $$' to get an interactively updated panel giving you the xrefs while you scroll in the disasm

    You can now script r2frida in the agent side in C. Thanks to the new CModule API the '.' command in r2frida handles the .c files in a special way

    Call code from an alive process with via \dxc (Dynamic eXecute Code). For instance, let's call getpid() from libc and then verify the pid with the cmd \dp. Any cool function to arbitrarily call from your target? Go and it!

    Refactoring news: The old r2 command "/c/" has been renamed to "/ad/". This command allows you to find assembly with regexes. Practical example; find assembly syscalls on obfuscated arm32 with r2 is a piece of cake.

    Command of the day: alias reset='r2 -qcre --' Yep, r2 also have the UNIX 'reset' command inside to restore/fix the terminal settings.

    When reviewing the XRefs in visual mode (press 'x'), now we can press ';' too add a comment in the caller in order to make clear the purpose of each call or if we are interested in them or not.

    Thanks to the RSoC this last 3.5.1 release also includes the new 'scr.prompt.popup' option to show the rollup widget when TAB is pressed to autocomplete the commandline. Combines with all your favourite color themes!

    The new r2pipe for Python (v1.3.1) comes with a new cmdJ() method that returns a Python object instead of a JSON one, so you can use dot and tab to autocomplete and introspect anything inside r2. Thanks for the addition!

    You can decode base64 strings in different ways. Use p6d and ?b64- commands to decode them. Check out the 📸 example.
