binfmt_misc (Miscellaneous Binary Format) is a capability of the Linux kernel which allows arbitrary executable file formats to be recognized and passed to certain user space applications, such as emulators and virtual machines. [1] It is one of a number of binary format handlers in the kernel that are involved in preparing a user-space program ...
It then uses the system C compiler to compile the source shell script and build a stripped binary which behaves exactly like the original script. Upon execution, the compiled binary will decrypt and execute the code with the shells'-c option. [2]
In addition to the binary application code, the executables may contain headers and tables with relocation and fixup information as well as various kinds of meta data. Among those formats listed, the ones in most common use are PE (on Microsoft Windows ), ELF (on Linux and most other versions of Unix ), Mach-O (on macOS and iOS ) and MZ (on DOS ).
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
Shell built-ins and system binary executable files of the same name often have differing options. "The project maintainer also has a Bash page which includes Frequently Asked Questions", [111] [110] this FAQ is current as of bash version 5.1 and is no longer updated.
Linux kernel boot and decompression process. vmlinux is a statically linked executable file that contains the Linux kernel in one of the object file formats supported by Linux, which includes Executable and Linkable Format (ELF) and Common Object File Format (COFF).

After the address information is the file offset the segment data is located in the Mach-O binary, and the number of bytes to read from the file. When the address size is larger than the number of bytes to read from the file, the rest of the bytes in RAM space are set 0x00 .
