command line - How to script FTP upload and download

Question

I'm attempting to make a batch file to upload a file to an FTP server. If I type it in manually it works fine, but when I run the batch file it halts after it's connected... It says:

connected to domain.com.

220 microsoft ftp server

User(domain.com:(none)):

And then nothing else. What is going on here?

Below is my batch file:

ftp www.domainhere.com

user useridhere

passwordhere

put test.txt

bye

pause

It's a reasonable idea to want to script an FTP session the way the original poster imagined, and that is the kind of thing Expect would help with. Batch files on Windows cannot do this.

But rather than doing cURL or Expect, you may find it easier to script the FTP interaction with PowerShell. It's a different model, in that you are not directly scripting the text to send to the FTP server. Instead you will use PowerShell to manipulate objects that generate the FTP dialogue for you.

Upload:

$File = "D:Devsomefilename.zip"
$ftp = "ftp://username:password@example.com/pub/incoming/somefilename.zip"

"ftp url: $ftp"

$webclient = New-Object System.Net.WebClient
$uri = New-Object System.Uri($ftp)

"Uploading $File..."

$webclient.UploadFile($uri, $File)

Download:

$File = "c:storesomefilename.zip"
$ftp = "ftp://username:password@example.com/pub/outbound/somefilename.zip"

"ftp url: $ftp"

$webclient = New-Object System.Net.WebClient
$uri = New-Object System.Uri($ftp)

"Downloading $File..."

$webclient.DownloadFile($uri, $File)

You need PowerShell to do this. If you are not aware, PowerShell is a shell like cmd.exe which runs your .bat files. But PowerShell runs .ps1 files, and is quite a bit more powerful. PowerShell is a free add-on to Windows and will be built-in to future versions of Windows. Get it here.
