1) Write a C program for Linux called pipes.c that does
the following: In the main() function, it creates a pipe
using the pipe() function, then creates two child processes with
fork(). Child 1 redirects stdout to the write end of the pipe and
then executes with execlp() the "ps -aux" command. Child 2
redirects its input from stdin to the read end of the pipe, then it
executes the "sort -r - n -k 5" command. After creating both
children, the parent process waits for them to terminate before it
can exit. Note that you may have to create Child 2 first, followed
by Child 1. The parent program does the same thing as a shell that
runs the command "ps -aux | sort -r -n -k 5". You must use the
fork(), pipe(), dup2(), close(), execlp() functions.
