Environment Variables and system() In this task, we study how environment variables are affected when a new program is executed via the system () function. This function is used to execute a command, but unlike execve(), which di- rectly executes a command, system() actually executes"/bin/sh -c command", i. e., it executes /bin/sh, and asks the shell to execute the command. If you look at the implementation of the system () function, you will see that it uses execito execute /bin/sh; execl() calls execve(). passing to it the environment variables array. Therefore, SEED Labs - Environment Variable and Set-UID Program Lab using system().the environment variables of the calling process is passed to the new program /bin/sh. Please compile and run the following program to verify this. #include include int main() system("/usr/bin/env"); return 0;
