Here's a minimal echo that does not handle options (-n, -e, etc.)

int main(int argc, char *argv[])
  int i;
  for (i = 1; i < argc; i++) printf("%s ", argv[i]);
  return 0;

echo command is nothing but printing of its arguments.

Note: above program not tested. Also has an obvious bug: prints an
extra space at the end if it has 1 or more arguments (I just wanted to
keep it simple).
