How to make Ubuntu commands make work on Windows

Question

My C code which runs on Ubuntu has line

system("ls -l | wc > temp.txt");

I want to make it work on windows so that It has to be OS Independent.How can I do that. Can any one help me?

Answer 1

I would guess that the particular code shown is probably going to get the first value from the "temp.txt" file at some point and use it as a count of files (actually number of files plus one)

Instead of that you could use C code like this

#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>

int main() {
DIR *cwd;
int c=1; /* like +1 */
struct dirent *d;
if ((cwd=opendir(".")) ) {
 while((d=readdir(cwd))) {
     if (*(d->d_name) != '.') c++; /* ignore dot files */
 }
} else {
    perror("opendir fail");
    return(1);
}
printf("the first number in temp.txt would be %d", c);
return(0);
}

Whatever the system() call result is doing, this is my answer: rewrite it in C, which you have working on both systems
