Curl download and delete file ftp

I need to download a file from a ftp server and delete it after is transferred (on remote server) It's possibly in a single command line?

curl ftp://host/testfile.txt -X 'GET testfile.txt' --user user:password -o local.txt
curl ftp://host/testfile.txt -X 'DELE testfile.txt' --user user:password

Thanks

WinSCP has an option -delete that you can combine either with put or get commands, to delete the source file after a succesfull change. This option lead me to move from curl to WinSCP, because now I can write simpler "transactional" scripts, and I'm sure that when I delete the original file from the "transfer" folder, it is because it was successfully delivered.

https://winscp.net/

https://winscp.net/eng/docs/scriptcommand_get

https://winscp.net/eng/docs/scriptcommand_put

However, curl is quite powerful for other types of scripts and URL management, nowadays I use a mix of both utilities depending on the task to be done.

Yes, it is possible to do this in a single command:

curl -Q '-DELE testfile.txt' --user user:password -o local.txt ftp://host/testfile.txt

From the man page:

-Q, --quote
       (FTP SFTP) Send an arbitrary command to the remote FTP  or  SFTP
       server.  Quote commands are sent BEFORE the transfer takes place
       (just after the initial PWD command in an FTP  transfer,  to  be
       exact). To make commands take place after a successful transfer,
       prefix them with a dash '-'.  To make  commands  be  sent  after
       curl has changed the working directory, just before the transfer
       command(s), prefix the command with a '+'  (this  is  only  sup‐
       ported for FTP). You may specify any number of commands.

I recommend creating a script of your FTP commands, and piping them into the built-in ftp client. Here's an example (replace the ls command in the test.ftpscript with your GET/DEL commands) that worked on my machine:

[user@host ~] cat > test.ftpscript user anonymous [email protected] ls bye [user@host ~] ftp -inv ftp.swfwmd.state.fl.us < test.ftpscript Connected to ftp.swfwmd.state.fl.us (204.76.241.31). 220 331 Please specify the password. 230 Login successful. 227 Entering Passive Mode (204,76,241,31,191,167). 150 Here comes the directory listing. -rw-r--r-- 1 0 0 7478 Dec 05 09:59 README.txt drwx------ 2 0 0 16384 Dec 04 13:40 lost+found drwxr-xr-x 20 0 0 4096 Dec 18 14:42 pub lrwxrwxrwx 1 0 0 3 Dec 05 10:07 public -> pub drwxr-xr-x 3 0 0 4096 Dec 04 15:26 pvt 226 Directory send OK. 221 Goodbye. [user@host ~]
