Ran into a piffling employment today, something I don’t actually produce ofttimes in addition to something many would never do! Yeah, I’m talking most FTP .. the former pre-historic service of a matter that was originally RFC’d dorsum inwards 1971. I had to mass delete files inwards FTP server, empty a folder in addition to delete that too. Sounds simple, but non really!
So this FTP server had some database in addition to the database got corrupted. Since the database got corrupted, the log directory but kept accumulating logs without deleting every bit none of the files got processed. Over time, it had most 145789 files sizes betwixt 400mb to 4gb. You know spider web logs, swells upwards when people wake upwards in addition to slows downwards when everyone off sleeping. Any how, in addition to hence right away I got to delete those 145789 files through former schoolhouse FTP. It’s supposed to endure like shooting fish in a barrel but noooo, I cannot purpose FileZilla or WinSCP or whatever GUI customer to brand my life easier. I convey to purpose CLI FTP. Let’s see:
ubuntu@ftp-client01: $ ftp
ftp> opened upwards ftp-server01
Connected to ftp-server01.
220 Welcome to the Web FTP service.

drwxrwx--- two ftp ftp 36864 Sep 06 07:37 testdatabase
226 Directory ship OK.
So far in addition to hence good, I logged inwards in addition to tin listing the directories. It seems there’s a exam database folder every bit well. Let’s banking concern gibe the contents commencement but to ensure I am looking at the correct thing.

Looks similar all adept in addition to laid upwards to go. Let’s create cli-kungfu on that earlier trying it on the master copy directory.
ftp> ?
Commands may endure abbreviated. Commands are:
! debug mdir qc send
$ dir mget sendport site
account disconnect mkdir rate size
append leave of absence mls pwd status

close ls prompt restart umask
cr macdef passive rmdir verbose
delete mdelete proxy runique ?
mdelete is definitely the agency to become every bit y'all tin delete many files. Let’s create that.
Now hang on, I don’t desire to confirm for each file, this is actually annoying in addition to fourth dimension consuming when y'all convey to produce it 14000 times! Let’s create something else similar rm -r or rmdir -r to produce recursive deletion.

ftp> rm -r testdatabase

221 Goodbye.
Alright, that was a fail! I searched or in addition to hence in addition to there’s in addition to hence piffling information most FTP in addition to how to delete non-empty folder or mass delete files from CLI. Everyone uses some GUI customer that allows y'all to confirm inwards bulk. Finally I constitute a way.
Apparently, y'all tin purpose usage -i flag to plow off interactive, in addition to hence FTP won’t prompt y'all for every employment when using mdelete. Hope it works:
ubuntu@ftp-client01: $ ftp -i
