You can /only/ do it through your shell's language.

The current working directory is part of the so-called "environment" of 
a process (i.e. a running program) - a collection of various information 
that is local to the process; there is exactly one situation where one 
process has control over another's environment: A new process will 
always start with its environment set to the same values as the process 
which started it. Aside from that, no process can tamper with the 
environment of another process - so no external program your shell could 
possibly start would have the ability to change the shell's working 
directory.

You will not find a "cd" command on /any/ Unix machine - it only exists 
as a built-in shell command.

(Assuming you're talking about some Unix variant here; but I guess other 
multitasking OS will handle the CWD in a similar fashion.)
