# lftp profile creation example
lftp -c "bookmark add SiteName ftp://user:password@sitename.com/path"
#lftp -c "bookmark add SiteName ftp://user:password@sitename.com:2121/path" # For a different FTP port

# If you are using SFTP it's better to use this line
#lftp -c "bookmark add SiteName sftp://user:password@sitename.com/path"
#lftp -c "bookmark add SiteName sftp://user:password@sitename.com:2121/path" # For a different FTP port

# lftp upload file
lftp -c "open SiteName && lcd MyLocalDir && mput ./"*

If you run into issues with SSL certificate verification the below should help.
NOTE: Even though we backup the original configuration, test this on a development server first.

# Disable SSL Verification - Start
# If you are running into problems with SSL certification verification
sudo cp /etc/lftp.conf /etc/lftp.conf.original_`date +%Y_%m_%d_%H.%M.%S`
sudo sed -i "/^\s*#/d;s/\s*#[^\"']*$//" /etc/lftp.conf && sudo sed -i '/^\s*$/d' /etc/lftp.conf
echo "set ssl:verify-certificate no" | sudo tee -a /etc/lftp.conf
# Disable SSL Verification - Stop
