[SOLVED] Unknown Command on automation with PowerScript

2012-02-20 16:03

Hi Guys,
I have created a PowerShell Script which automatically downloads files from a FTP Server.
The connection has to be a SFTP Connection with a Private Key.
That's why I am using WinSCP - thanks for this great piece of software!

Now I'm getting the following error and I have no idea to rid it of..
My code looks like this (just a small part..):

$Script += "open sftp://$username@$FTPServer -privatekey=$PPKfile -hostkey=$SFTPFingerprint"

As you can see I'm adding some text with vaiables to the Array $Script.
Because the $SFTPFingerprint contains spaces I am defining the variable as following:

$SFTPFingerprint = '"ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"'

When I am writing the array to a text file I receive the following result:

option batch abort option confirm off open sftp://user@server -privatekey=C:\Scripts\FTPTransfer\keyfile.ppk -hostkey="ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx" cd /folger/subfolder option transfer binary get -delete * C:\Scripts\Temp\ close exit

Now I receive this error message: Unknown command '1024'.
Afer searching the forums I found a Link to this ticket: https://winscp.net/tracker/494

Does somebody got an idea?

Looks like you are not adding newlines after every command.

Hi prikryl,
do I have to?

I am starting the script with this line:

.\WinSCP.com /command $script /log=$ScriptFolder\LogWINSCP.txt

That means I am directly writing the %script to the /command.

In real it would look like:

.\WinSCP.com /command option batch abort option confirm off open sftp://user@server -privatekey=C:\Scripts\FTPTransfer\keyfile.ppk -hostkey="ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx" cd /folger/subfolder option transfer binary get -delete * C:\Scripts\Temp\ close exit /log=C:\Scripts\LogWINSCP.txt

Ok, I've though you are writting the command to a file.
If you case, you need to enclose every command into double quotes.

.\WinSCP.com /log=C:\Scripts\LogWINSCP.txt /command "option batch abort" "option confirm off" "open sftp://user@server -privatekey=C:\Scripts\FTPTransfer\keyfile.ppk -hostkey=""ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx""" "cd /folger/subfolder" "option transfer binary" "get -delete * C:\Scripts\Temp\" close exit

"option batch abort" "option confirm off" "open sftp://user@server -privatekey=C:\Scripts\FTPTransfer\keyfile.ppk -hostkey="ssh-rsa 1024 38:9c:d5:da:b1:d3:dc:3f:46:42:40:f9:75:ca:7e:f0"" "cd /home/from" "option transfer binary" "get -delete * C:\Scripts\Temp\" close exit
