Formats currently supported: asm, bin, hex, obj, exe, C, python, ruby, pretty, safeasm, completec, shellstorm.<\/li>\n<li>    Interactive asm-to-opcode conversion (and viceversa) mode. This is useful when you cannot use specific bytes in the shellcode.<\/li>\n<li>    Support for both ATT &#038; Intel syntax. Check the &#8211;intel switch.<\/li>\n<li>    Support for 32 and 64 bits (when playing on x86_64 machine). Check the &#8211;64 switch.<\/li>\n<li>    Resolve syscall numbers, constants, and error numbers (now implemented for real! :-)).<\/li>\n<li>    Portable and easily deployable (it only relies on gcc\/as\/objdump and python).<\/li>\n<li>    It is just one self-contained python script, and it supports both Python2.7+ and Python3+.<\/li>\n<li>    In-place development: you run ShellNoob directly on the target architecture!<\/li>\n<li>    Built-in support for Linux\/x86, Linux\/x86_64, Linux\/ARM, FreeBSD\/x86, FreeBSD\/x86_64.<\/li>\n<li>    &#8220;Prepend breakpoint&#8221; option. Check the -c switch.<\/li>\n<li>    Read from stdin \/ write to stdout support (use &#8220;-&#8221; as filename)<\/li>\n<li>    Uber cheap debugging: check the &#8211;to-strace and &#8211;to-gdb option!<\/li>\n<li>    Use ShellNoob as a Python module in your scripts! Check the &#8220;ShellNoob as a library&#8221; section.<\/li>\n<li>    Verbose mode shows the low-level steps of the conversion: useful to debug \/ understand \/ learn!<\/li>\n<li>    Extra plugins: binary patching made easy with the &#8211;file-patch, &#8211;vm-patch, &#8211;fork-nopper options!
