9 processes executing the same program, but each process has its own copy
10 of the program within its own address space and executes it

49 The easy way to run another program is to use the @code{system}

155 A newly forked child process continues to execute the same program as
158 @code{_Fork} to tell whether the program is running in the parent process
162 Having several processes run the same program is only occasionally
163 useful.  But the child can execute another program using one of the
164 @code{exec} functions; see @ref{Executing a File}.  The program that the
166 execution of a new program causes the process to forget all about its
167 previous process image; when the new program exits, the process exits

870 Remember that the first @code{argv} argument supplied to the program
871 represents the name of the program being executed.  That is why, in the
872 call to @code{execl}, @code{SHELL} is supplied once to name the program
