Overview
An executable file (or program) is a file that contains instructions, or machine code, directly executable by the CPU. The alternative is a file that contains higher level instructions or code to be interpreted by an interpreter. The executable files are usually created by assembling object files, which are created by compiling a higher level language.
Linux operating systems use Executable and Linkable Format (ELF).
MacOS uses Mach-O.
One can tell the format by executing the file command on the executable file.
On Linux:
On Mac:
file yunikorn-scheduler
yunikorn-scheduler: Mach-O 64-bit executable x86_64
The format of the machine code stored in an executable file depends on the machine architecture.
