Assuming root access, what would be a simple way to copy a single file into each directory on the box.  So if there were 1,000 directories, there would then be 1,000 copies of the file.

Conversely, what would be the simple way to remove the same files.

Do you really want 1000 copies of the same file, or would using hard links reference the same file in multiple locations?
Find . -type d | while read a; do
The -d tells it to find directories.

The exec method will error out because of too many elements being passed. Using xargs might be a better choice.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

@arnold    find will only pass 1 arg at a time, so exec will be fine.  potentially eat a lot of disk space, but work.  

hard/soft links would be better if the file isn't going to be changing, Identifying the file-system splits would vary depending on OS, (unless you issued a df for each directory to see where it lived.... but, this would be nuts on large systems).

Thanks for the great comments - I really do need multiple copies of the same file, not links.  This is a testing situation.
