What I want to do is copy all the *.js files in the source folder to the destination folder recursively. I also don't want to overwrite any files that are already present in the destination folder. Any thoughts of how to accomplish this?
I tried using
cp -n source/**.js desination/ and
cp -Rn source/**.js desination/ after looking at another similar question, but it doesn't seem to be working.
Any idea how to accomplish this?
