What are all the things a child process can/will inherit from a parent? (and some other related questions)...

What properties of an unprivileged process are preserved during an `execve` call?

How do fork and exec work?

I am trying to get a big picture / "umbrella" perspective here.
As of now, I only know that a child process will inherit from a parent by default its "file descriptors".
- Also, I somehow understand (but am not sure if I am right) that "file descriptors" are an "attribute" of a process, and a process has many attributes. Am I right?
- Can a child inherit anything else other than attributes?
- What are all the attributes that a process might have? (is there a reference page/manual for this?)
- What attributes (or any non-attributes, reference to question (1)) does a child process inherit by default from its parent?
- Are "processes", "attributes" and "file descriptors", and process inheritance, a unique concept to UNIX operating systems, or are they also present in non-UNIX operating systems?

A fork() is a forking, everything is inherited, you get two mostly exact copies of the process (except for the return value offork()in both processes and the pid, ppid obviously). Maybe the question you wanted to ask is what is preserved when a process executes a new command.

A fork() is a forking, everything is inherited, you get two mostly exact copies of the process (except for the return value offork()in both processes and the pid, ppid obviously). Maybe the question you wanted to ask is what is preserved when a process executes a new command.
