- Child process
A child process in computing is a process created by another process the parent process . A child process inherits most of its Attribute computing attribute s, such as open computer file file s, from its parent. In Unix UNIX , a child process is in fact created using fork operating system fork as a copy of the parent. The child process can then overlay operating system overlay itself with a different program using tt Exec operating system exec tt as required. Each process may create many child processes but will have at most one parent process if a process does not have a parent this usually indicates that it was created directly by the kernel computer science kernel . In some systems, including UNIX based systems such as Linux , the very first process called init is started by the kernel at booting time and never terminates see Linux startup process other parentless processes may be launched to carry out various daemon computing daemon tasks in userspace . Another way for a process to end up without a parent is if its parent dies, leaving an orphan process but in this case it will shortly be adopted by init.
