The simplest way to access a ftp server with username and password curl ftp://myftpsite.com --user myname:mypassword </span> With the command line above, curl will try to connect to the ftp server and list all the directories and files in the ftp home directory. To download a file from ftp server curl ftp://myftpsite.com/mp3/mozart_piano_sonata.zip --user myname:mypassword -o mozart_piano_sonata.zip</span> To upload a file to ftp server curl -T koc_dance.mp3 ftp://myftpsite.com/mp3/ --user myname:mypassword</span> To list files in sub directories. curl ftp://myftpsite.com/mp3/ --user myname:mypassword</span> List only directories, silent the curl progress bar, and use grep to filter curl ftp://myftpsite.com --user myname:mypassword -s | grep ^d</span> Remove files from ftp server. This is a bit tricky, because curl do not support that by default, well anyway, you can make use of -X and pass in the REAL FTP command. (Check out a list of FTP service Command in rfc 959, under 4.1.3. FTP SERVICE COMMANDS) curl ftp://myftpsite.com/ -X 'DELE mp3/koc_dance.mp3' --user myname:mypassword</span> Caution: Make sure you are know what are you deleting! It will not prompts ‘Are you sure?’ confirmation. Check out curl manual for more, man curl</span> or this, ^^ (contains different info) curl --manual | less </span>
