Hi,

i run node-red on a IOT2000 module from Siemens.  
I need to mount a shared folder from windows.  
It works if I do it with Putty (command promp).  
I send:  
`mount.cifs //192.168.1.58/Share /Recepten –o user=Iedereen`  
Then I get back :  
`Password for root@192.168.1.58/Share:`  
Since I don't have a password I just pres [enter] and it works.

Now I have to do this with node-red (so I can do it automaticly evertytime it boot up)  
I can send the first command:  
`mount.cifs //192.168.1.58/Share /Recepten –o user=Iedereen`  
But then I get back:  
`Password for root@192.168.1.58/Share:`

But how I need to answer on this? Do I need two exec nodes?  
I don't know how to deal with this in node-red

Have you tried adding `\n` at the end?

`mount.cifs //192.168.1.58/Share /Recepten –o user=Iedereen\n`

Actually that probably won't work. Its obviously entering the CMD. You want enter after the command responds.

Sure it's possible, but don't know at the moment. Sorry.

I've already tried that.  
Also with 2 nodes in a row, or in parallel with a delay in between.  
Without success.  
Thank you for thinking along

Try....  
`mount.cifs //192.168.1.58/Share /Recepten –o user=Iedereen password=`

Or

`mount.cifs //192.168.1.58/Share /Recepten –o user=Iedereen, password=`

The exec node is only really designed to run "one" command. you may be able to do something like

```auto
echo | mount.cifs //192.168.1.58/Share /Recepten –o user=Iedereen

```

that may work - or the enter may get sent too quick...

The node-red-node-daemon node could be an alternative as that leaves the input side open for use as stdin so you can inject extra commands into the process at any time.

I have also try that already, but that doesn't seems to work for my module. Even with putty he still asks for a password

Yes! That is working!  
`echo | mount.cifs //192.168.1.58/Share /Recepten –o user=Iedereen`

Can you explain what the 'echo |' does?  
Thank you !!!

A different solution, for future readers finding this topic, would be to use `expect` and a script for it. I use it to insert non-empty passwords into processes without having to store the passwords in plain text in scripts or flows. This article is how I got started with expect: [https://likegeeks.com/expect-command/](https://likegeeks.com/expect-command/)  
Does the job for me wherever I need it to. This situation is slightly easier so `echo | ...` works just fine too.

echo {something} | command - will pipe "something" into the command... and automatically adds an enter - so echo | will just send enter to the command. As long as that is all you needed then phew... anything more complex than a single word plus enter then use the expect command/script as suggested by @afelix
