Re: How can I use system cmd with variables?

I am not aware of any such function in any programming language.  All of them
provide generic functions that do one or another.  The distinction is just
not made in the kernel of the OSes as the actions as moving is just a 
generalization of renaming.

In UNIX there is no rename command.  People are accustomed to using 'mv' for
doing either operation.  

Ok.  I think if you do move_file( "dir1\\file1", "file2" ) it will probably
also move the file to dir1, which is not what you want.  With system however,
the user could inject code strings.  Like with SQL injection attacks.

If you are curious about other renaming programs there is one available for
Linux and it is distributed on the Puppy Linux CD.  That version of Linux 
runs out of memory that is loaded from the CD.  So you don't have to
mess with your computer's hard drive.
