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).
In Unix and other POSIX-compatible systems, the parent process can retrieve the exit status of a child process using the wait() family of system calls defined in wait.h. [10] Of these, the waitid() [ 11 ] call retrieves the full exit status, but the older wait() and waitpid() [ 12 ] calls retrieve only the least significant 8 bits of the exit ...
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.
Scripting languages are, by definition, able to be extended; for example, a MS-DOS/Windows 95/98 and Windows NT type systems allows for shell/batch programs to call tools like KiXtart, QBasic, various BASIC, Rexx, Perl, and Python implementations, the Windows Script Host and its installed engines. On Unix and other POSIX-compliant systems, awk ...
The original DOS executable file format. These formats can be identified by the letters "MZ" at the beginning of the file in ASCII. Later formats may contain an MZ DOS stub header. [2] 16-bit New Executable (NE) Introduced with the multitasking MS-DOS 4.0 and also used by 16-bit OS/2 and Windows, NE can be identified by the "NE" in ASCII.
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 ...

The SCM executable, Services.exe, runs as a Windows console program and is launched by the Wininit process early during the system startup. [2] Its main function, SvcCtrlMain(), launches all the services configured for automatic startup. First an internal database of installed services is initialized by reading the following two registry keys:
