Delete recursive directories with FTP command on Bash
Solution 1:
Use lftp. The the -r option to lftp rm recursively deletes directories and files.
$ lftp -u <user>,<pass> <server>
lftp> rm -r <directory>
should do the trick.
Solution 2:
The lftp command, which is available in many distros (though I'm no SUSE expert), supports "rm -r" for exactly that purpose.
