Q$4.$ Write a program in C to simulate the output redirection using the dup family of system calls$($dup$,$ dup$2,$ dup$3).$

$[20$ points$]$

This program consists of $2$ parts :

Part $1$: Simple Output Redirection

$-$ Implement a function

$-$ That opens a file for writing $($From user$)$

$-$ Uses dup $/$ dup$2$ to redirect stdout to file

$-$ Prints some random text to the redirected stdout

$-$ Verify that the data is written in the file.

$./$q$4-$p$1$ output$\_$p$1.$txt $//$ output.txt must contain some random text

Part $2$: Interactive Simulation

$-$ Simulate a simple shell$-$like command that redirects the stdout and stderr of any internal command into a file. Eg :

$./$q$4-$p$2"$ls $-$l$"$ output$\_$p$2.$txt $//$ output.txt must contain the output of Is $-$I

Deliverables:

$-$ Q$4.$c containing the implementation for both parts $($We should be able to test the implementation of both parts$)$

$-$ Makefile to compile the program

$-$ output$\_$p$1.$txt and output$\_$p$2.$txt containing the output from both parts.
