If I have a list of URLs separated by \n, are there any options I can pass to wget to download all the URLs and save them to the current directory, but only if the files don't already exist?

There is a -nc (--no-clobber) option for wget.

From wget --help:

....
-i,  --input-file=FILE     download URLs found in local or external FILE.
....
-nc, --no-clobber          skip downloads that would download to
                           existing files.
-c,  --continue            resume getting a partially-downloaded file.
....

I've included --continue because it seemed like it might be helpful if you're trying to recover from an interrupted download, but you don't need it to answer your original question.
