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.
