lftp -u FTP_USER,FTP_PASS -e 'mirror REMOTE_DIRECTORY LOCAL_DIRECTORY' FTP_SERVER

Ако излезе тази грешка:
mirror: Fatal error: Certificate verification: certificate common name doesn't match requested host name ‘FTP_SERVER’
1 error detected

Фикса е:

echo "set ssl:verify-certificate no" >> ~/.lftp/rc
