I had to fetch a few thousand files across a few directories on a remote server recently and I was going to use NCFTP, however I’d remembered that the stock ftp program on linux can in fact do a recursive fetch. You need to remember to turn the interactive prompts off as well, because if you don’t then you will have to press the ‘Y’ key to download each file.
# Open connection ftp email@example.com
Turn the interactive prompt off
# Use the command ‘mget’ to fetch the files, the glob (*) will execute
on the remove server
