e/Fork-exec

Information
has gloss	eng: Fork-exec is a commonly used technique in Unix whereby an executing process spawns a new program. fork is the name of the system call that the parent process uses to "divide" itself ("fork") into two identical processes. After calling fork, the created child process is actually an exact copy of the parent - which would probably be of limited use - so it replaces itself with another process using the system call exec.
