Implementing terminal commands with c

Question

I have to write the c program that executes terminal commands which are in this order :

so if I have attack.c then by ./attack, all these should be implemented on the terminal. I tried using execvp() but its just not happening.

Question is kind of similar but the solution is not working.I just want like a conversion of these four commands — Aditi Garg Sharma, Oct 14 '18 at 10:43

You can run shell commands in C using the system() command (works in linux)

#include <stdio.h>
#include <stdlib.h>
int main() {
  system("cd ../../etc; chmod a + x file; cd alice/password; cat password");
  return 0;
}

Bonus: figure out why this doesn't do what I think you want. – stolenmoment Oct 14 '18 at 11:47
