Hi mates,
i am trying to run a shell command from my C program in this case let is say the "ls" command. It copiles it okay, and even creates the new fork too. But seems to nothing is happening i mean it is not showing the result of the "ls" command.

I don't know wat i am doing wrong. Any comment will be appreciated.

#include <unistd.h>
#include <sys/wait.h>
#include <stdio.h>

int p_id;
int child_status;
int cpid;

main()
{
cpid=fork();

switch (cpid)
{
case -1:
perror("fork");
exit(1);
case 0:
printf("The fork is successful!\n");
system('ls');
exit(0);
default:
wait(&child_status);
}
}

It worked for me with a slight change.

system("ls");


BTW: Please post C related questions in "C Programming in the UNIX Environment" section. Thanks.
