Ftp skip file download if already exists

Thx, Adrian. Join Date: Jul Just type a? I already knew that, the question was : How to avoid overriding which is equivalent to test if a file on remote exists I wanted command line tools I've said I am using a script. Please answer to the question specifically.

Hi there, I am sorry to ask that kind of beginner thing, but all the code I found online didnt work for me. The SSH login has to be with username and password. So I would be very thankful if somebody could write the line Shell Programming and Scripting.

Except script fails to check file exists or not in remote node. However the result is always found even if the file exist or doesn't exist.

Sorry, something went wrong. Continue downloading a partially downloaded file. Use this option to resume a download started by a web browser or another program which downloads files sequentially from the beginning. So it also doesn't download if the file is already "downloaded"? FTP server ftp. Note this only checks for the existence of the file, not it's modified date: for filename in ftp.

If you don't need to do this in code, you could use something like rsync which is build to do that sort of thing. There are windows ports of rsync. There are plenty of APIs in os. For example os. Also, you might want to change that password now that it's been posted on the internets.

I hope you don't use it on any other websites Thanks for the edits, posted the question in a hurry and forgot to change the pass It's not used for anything else though, luckily — Dryden Long. My first instinct is to do something like: os.
