i = system ("cd c:\text"); :(

Expand Post »

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
int main ()
{
  int i,j;
  puts ("Trying to execute command CD ");
  i = system ("cd c:\text"); 
  if (i==-1) puts ("Error executing CD");
  else puts ("Command successfully executed");

 puts ("Trying to execute command del ");
  j = system ("del *.txt"); 
  if (j==-1) puts ("Error executing del");
  else puts ("Command successfully executed");

 getchar();
  return 0;
}

It won't work. How do I make this go to a specific directory? I know if i just make it i = system ("cd"); that it will print the current directory. Is there a way to change directories this way?

Re: i = system ("cd c:\text"); :(

system actually starts a new process, does what you want, then closes that process. in fact, if you really think about it, what does it mean to "change directory"; "change directory" or cd is a Shell implemented feature on the *system* level. With this in mind, you're best bet is to use the standard unix library.

#include <unistd.h>

and the function chdir(char *path)

man chdir
man getcwd

system is the worst function of all time, never use it.

I'm sorry, at a closer look you are using Windows...I thought you were actually using C on a Unix System. I'm not sure how you'd do it with the Win32 API, I'd imagine it is quite similar.

Shouldn�t system(�cd c:\text�);
be system(�cd c:\\text�);

Yes.

chdir("c:\\text");

By the way subtronic, on windows the chdir() function is in dir.h. Thanks alot for all the help guys
