I refuse to use vi so my only (?) option is this. Copy the file in question either in x-term or whatever you use on PC side after ssh-ing to your n8x0 to a memory card. Connect via usb to your PC. You should be able to see this file now (if prefixed with period you wont, I use TextWrangler on OS X to see/edit invisible files). When finished copy it back to wherever it came from.
