Very Computer

I want to change a directory from within a program ,
i tried the following :

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

main()
{
  system("cd ..");
  system("pwd");
  return 0;

Quote:}

This will not work (because system uses fork and execxx ?) .
I tried to use instead :
system(". cd ..");
which will not work either , to start cd with a leading point seems
to be impossible .
Does anyone know how it can be done ?

Thanks in advance,
Martin

Try this

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

main()
{
  char buff[255];

  printf("%s\n", getcwd(buff, 255));
  chdir("/");
  printf("%s\n", getcwd(buff, 255));

  return 0;

There is no escaping the fact that system() function uses a
subshell to execute the argument as a command.

Do "man 2 chdir" for a system call to change the current working
directory directory.

General advice : avoid the temptation to do this:
        system (" some familiar command" );
C is not bourne shell script.

See man chdir for information on how to do it properly.
