A customer of mine is making some files available to me on an FTP server. As I need those locally, I searched around for a solution to synchronize those files to a local folder.
I have found the great tool called lftp which is available from the Ubuntu’s repositories. I use that command in a crontab:
lftp ftp://user:firstname.lastname@example.org -e "mirror -e / /path/to/my/local/folder ; quit"
