The man page for ftp lists the sunique and runique FTP subcommands which toggle saving files with unique filenames, as a way of avoiding overwriting existing files:

ie, file.1 if file exists, file.2 if file.1 exists, etc.

These are ftp commands, not OS command-line options for ftp, but I think the .netrc file could be used to toggle sunique or runique from the default OFF state when ftp starts.

I am not worry about overwriting, just writing the same file again when i dont need to (thus the skipping which i forgot to mention!). Can i use sunique to plainly skip a file? I am thinking i should wipe the remote folder and start clean early during the day. – acidzombie24 Nov 11 '09 at 7:09

Between two Unix-based systems, why not just use rsync instead? It was written precisely to solve this problem.

In addition to the other answers posted, wget should do anything you require quite easily.

That's quite an odd (or creative) use of wget. How would one use that? – Arjan Nov 11 '09 at 8:16
would i need a wput ;). The machine on the other send (ftp host) is a windows while this one is a mac. – acidzombie24 Nov 11 '09 at 10:25
Arjan, "wget --no-clobber -c sunsite.doc.ic.ac.uk/ls-lR.Z"; will download all files from the FTP site at sunsite, while not clobbering local files. Acidzombie, there are wget binaries available for the Mac (install via Fink) and Windows (wget.addictivecode.org/FrequentlyAskedQuestions#download). – CarlF Nov 11 '09 at 15:14
Wget for the win! I'm up-voting this one. – pbr Nov 12 '09 at 22:10
