Making numerous virtual copies of a single file
I have to put a single/identical file to numerous different directories on a website and update them simultaneously and identically.

If I have the master file in directory a/, how can I make a "virtual copy" of this file into an other directory, in a way that any changes to the master file will be immediately and identically reflected in the virtual copy?

Thanks a lot!

What kind of file is this, exactly ? A 'content' file ? A "meta" file (like css), or a 'content access' file (like .htaccess).
I only ask because if this is a file that will be periodically (or episodically) altered, the way you 'dup' it may have an effect on the web site. AND if the web/application server MODIFIES this file, there may be other considerations (like revisoning).

Now to answer the question, I would think that soft-links to the 'master' file would be an easy & relatively safe way to do it. It should be fairly easy, once the master is created to create the soft-links from the command line or a script. Whether you use relative or absolute soft-links depends on how you think this web site may change in the future.

use the symlinks ... it will make figuring out which files the links are pointing to a lot easier to see ...
