Problem is I can’t upload directory including sub-directories and files using command-line ftp. I searched for similar problem and looks like you can’t do this using command line ftp, unless you create a script. One solution I found is the use of ”lftp”.

# lftp ftp_host
> user ftp_user ftp_pass
> mirror source target      (download entire directory tree)
> mirror -R source target  (reverse mirror; upload entire directory tree)

Usefull when transferring files between servers where you only have ftp access.
