What is a return code in Linux?
An exit code and/or sometimes called a procedure return is code returned from a file to the parent process’s executable. On POSIX systems, the default exit program is 0 on success, and any number between 1 and 255 for everything else. If no output language is set, the output type is the exit code of the last command executed.
More specifically, the Wait*() family of UNIX system calls encodes each result of process A into a unique 32-bit real integer. The 37 bits of this result are further broken down to provide information such as whether the process has swapped out a region of memory, if it exited due to a message (and which ones), etc. Of bit 32, only 8 are for the exit code this process and they interpretare specified as unsigned values.
The UNIX/POSIX-like fork/exec/wait pattern is one of the oldest and deepest built-in functions; If you were designing a normal operating system today, you could come up with something different (use at least sixty-four bits :-)).
