Full native implementation without dependency to external libraries.

=={{header|Batch File}}==

This uses the native FTP.EXE in Windows. I am not sure, but I think FTP.EXE client does not support passive mode.

=={{header|FutureBasic}}==

FB for Mac easily interfaces with the terminal command line. NOTE: The curl command line tool used in this example offers upload and sending capabilities. It supports FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS, FILE, POP3, IMAP, SMTP, RTMP and RTSP.

=={{header|Go}}==

Using the FTP package from [https://godoc.org/github.com/stacktic/ftp github.com/stacktic/ftp].

import (

fmt.Println("Wrote", n, "bytes to", file)

Dependencies are automatically loaded with the @Grab annotation.

let's say the code is saved in the file ftpTest.groovy:

@Grab(group='commons-net', module='commons-net', version='2.0')

import org.apache.commons.net.ftp.FTPClient

}

println(" ...Done.");

By typing groovy ftpTest.groovy, you should see a README.html file on your directory.

<pre>

Example uses [https://hackage.haskell.org/package/ftphs <tt>ftphs</tt>] package:

import Control.Exception (bracket)

-- Download in binary mode

(fileData, _) <- getbinary h "linux-0.01.tar.gz.sign"

=={{header|Java}}==

requires apache.commons.net

import java.io.IOException;

import java.io.OutputStream;

}

}

Output:

{{works with|Julia|0.6}}

ftp = FTP(hostname = "ftp.ed.ac.uk", username = "anonymous")

bytes = read(download(ftp, "make.notes.tar"))

=={{header|Kotlin}}==

</pre>

Next, you need to compile the following Kotlin program, linking against ftplib.klib.

import kotlinx.cinterop.*

FtpQuit(vnbuf)

nativeHeap.free(nbuf)

Finally, the resulting .kexe file should be executed producing something similar to the following output:

<pre>

=={{header|Lingo}}==

{{libheader|Curl Xtra}}

ch = xtra("Curl").new()

url = "ftp://domain.com"

ch.setOption(CURLOPT_URL, url & filename)

ch.setDestinationFile(_movie.path & filename)

=={{header|LiveCode}}==

put url "ftp://ftp.hq.nasa.gov/" into listing

repeat for each line ftpln in listing

e.g. to know the working directory, issue "pwd", we could issue "list" for above too,

but using an url with slash on the end with the ftp protocol causes a dir listing by default.

=={{header|Tcl}}==

===Using package ftp===

package require ftp

::ftp::Type $conn binary

::ftp::Get $conn README README

===Using a virtual file system===

An alternative approach that uses the package [http://sourceforge.net/projects/tclvfs/ TclVFS] to access ftp:// paths as a virtual file system.

package require vfs::urltype

vfs::urltype::Mount ftp

}

file copy README [file join $dir README]

The file <tt>vfsftpfix.tcl</tt> with the passive mode patch (see http://wiki.tcl.tk/12837):

# Replace vfs::ftp::Mount to enable vfs::ftp to work in passive

# mode and make that the default.

return $fd

}

=={{header|UNIX Shell}}==

Uses sftp which os available on all Linux distress by default. The commands are identical to ftp. This example uses the public free sftp server at test.rebex.net , the credentials are demo/password :

Aamrun $ sftp demo@test.rebex.net

Password:

sftp> exit

Aamrun$

=={{header|Wren}}==

{{libheader|ftplib}}

An embedded program so we can ask the C host to communicate with ''ftplib'' for us.

var FTPLIB_CONNMODE = 1

ftp.dir("", ".")

ftp.get("ftp.README", "README", FTPLIB_ASCII)

<br>

We now embed this in the following C program, compile and run it.

#include <stdio_ext.h>

#include <stdlib.h>

free(script);

return 0;

=={{header|zkl}}==

Using the cURL library, doing this from the REPL. Moving around in the tree isn't supported.

zkl: var d=cURL().get("ftp.hq.nasa.gov/pub/issoutreach/Living in Space Stories (MP3 Files)/")

L(Data(2,567),1630,23) // downloaded listing, 1630 bytes of header, 23 bytes of trailer

L(Data(1,136,358),1681,23)

zkl: File("foo.mp3","w").write(d[0][1681,-23])

The resulting file foo.mp3 has a nice six minute description of what can happen when returning from space.
