It does *to the extent possible*, i.e. if the platform you run this
on can get the job done without use of temp files, it will.  But note
that the fact that a command called "CD" (in upper case) even exists,
and prints the current directory if invoked without arguments, is
already completely non-portable.

You'll be a lot more portable using the POSIX standardized function
getcwd().

As to walking through trees: did you have a look at DJGPP's "ftw" for
"file tree walker" special function?
