[UPHPU] Bash scripting question

[Richard K Miller]

I've created a Bash script to copy a WordPress plugin to every  
WordPress installation on our server:

http://pastebin.com/f191ee2b9

On line 13, the cp command uses the -n flag to not overwrite existing  
files. I'd prefer to use the -i flag so that I'm prompted whether I  
want to overwrite existing files. However, the -i flag doesn't work in  
the xargs loop. It simply loops through each file and answers with the  
default "no" for each prompt.

Can I make the xargs/cp loop actually ask me whether I want to  
overwrite existing files?
