I'm trying to set up a script that will synchronise all images in a remote FTP directory with a local directory that I can run on a regular basis to make sure I have all new images added to the remote directory. I've been trying a solution using wget but I just can't seem to get the syntax right. Here is what I have:

wget -r -N --no-remove-listing -nd

All this seems to do is create a local index.html file with a list of links to remote files (which I don't want). How do I modify this command so it just downloads all the images in the remote directory? Alternatively, is there another unix command I can try to synchronise images from a remote FTP site?

Somebody suggested to me to use lftp command ( like this:

lftp -c 'open; user username password; mirror -e --only-missing images .; quit'

Seems to work nicely and it's built into most flavours of Unix.

You could try also ncftpget from the ncftp package. See but try to install a ncftp package for your distro.

From "man ncftpget"

-R      Recursive mode; copy whole directory trees.

You  can retrieve an entire directory tree of files by using the -R flag.  However, this will work only if the remote FTP server is a UNIX server, or emulates UNIX's list output.

       $ ncftpget -R /tmp /pub/ncftp

I've not used this command before - if you run it again will it ignore any files on the remote FTP server that already exist on the local file system? – Stephen Feb 16 '11 at 11:41
Sorry, I don't remember it, just try it out. – rems Feb 16 '11 at 16:40

If you want to use WGET, try using the A switch to specify the accepted file extensions:

wget -r --accept=jpg,gif,png*
