WaitForStrings with the possibility of different prompts returned
In a VBscript, I'm issuing an SSH command. When that SSH is performed, there are two possibilities:
1) the prompt will change to "[admin@xyz123 ~]$ "
2) the VM will ask for the admin passowrd to complete the SSH, where the prompt will look like:
admin@'s password:

I was trying to figure out how to do a "crt.Screen.WaitForString" where the script waits for either prompt and then takes action based on which prompt is returned.

I'm having a little difficulty getting an example working. From looking at the docs, I was thinking it should look something like:
result = crt.screen.WaitForStrings("admin@'s password: ", "[admin@xyz123 ~]$ ", 10)
If result = 1 Then crt.screen.send "testl"
If result = 2 Then crt.screen.send "test2"
If result = 0 Then
MsgBox "Error: Timed out waiting for prompt!"
End If

Thanks for any help!

Hi Reno,

Your code looks fine to me (and worked for me in a quick test). I did add a synchronous statement (and used crt.Dialog.MessageBox for all cases rather than send something to the remote):

crt.Screen.Synchronous = True
crt.Screen.Send "ssh" & vbcr
result = crt.screen.WaitForStrings("assword: ", "~]$ ", 10)
If result = 1 Then crt.Dialog.MessageBox "Received password prompt"
If result = 2 Then crt.Dialog.MessageBox "Already logged in as user"
If result = 0 Then crt.Dialog.Messagebox "Error: Timed out waiting for prompt!"

What were your results?

I got it working. I pasted in your code and then changed out the values with mine. That's all I did. Maybe there was something just a little off in the example I pasted.

One things I know, is when I get this things figured out, I'll forever have working examples to copy off myself instead of having to ask questions.

I really appreciate the help. Thank you sir!
