This program must compile with basic gcc function within linux.

Update the program to display the file size, owner ID, and file permission of the file.

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>

int main(int argc, char *argv[])
{
struct stat buf;

if (stat(argv[1], &buf) < 0 ) {
printf("Error ");
exit(-1);
}

if (S_ISREG(buf.st_mode))
{
printf("%s: regular file ", argv[1]);
}
else if (S_ISDIR(buf.st_mode))
{
printf("%s: directory ", argv[1]);
}
else
{
printf("%s: unknown type ", argv[1]);
}

return 0;
}
