Hi again! Yesterday I tried something, I remember I found it very stupidly! I wanted to get a filename as an argument and then put it into a variable and put it into a system(); statement! So it got something like this:

Code:

#include<stdio.h>
#include<stdlib.h>

int main(int argc, char *argv[])
{
if ( argc < 2)
{
printf("Usage copy [file1] [target]\n");
return 0;
}
else
{
system("copy" argv[1] argv[2]);
return 0;
}

Of course it didn't work because the statement system() does not allow this, but then I asked myself: How to make it diferent?
And now I ask you! Could you help me...? Thanx! [email protected] !

You need to concatenate your arguments into the string. This is easiest with strcat()

Code:

#include<string.h>
.
int PLENTYOFSPACE= 
char buffer[PLENTYOFSPACE]
strcpy(buffer,"copy ");
strcat(buffer,argv[1]);
strcat(buffer," ");
strcat(buffer,argv[2]);
system(buffer);

Code:

int main(int ArgCount, char* Args[])
{
   char Buffer[1024] = {0};
   if(ArgCount >= 3)
   {
      strcpy(Buffer, "copy ");
      strcat(Buffer, Args[1]);
      strcat(Buffer, " ");
      strcat(Buffer, Args[2]);
      System(Buffer);
   }   
   return 0;
}

That all looks pretty horrible.... why not write your own copy program and stop using that systen() function. It's easy enough, and has been done many times before.
