how to handle y/n response in .rsc script

Mon Apr 19, 2010 7:54 pm

So i have a basic script in .rsc file that I drag and drop. Through terminal I type "import scriptx"
When it gets to end of script it ask " Are you sure you want to upgrade y/n"
How can I include "Yes" in the script so the script doesn't halt?

Help is much Appreciated!
Thanks

I'm glad you asked this question!

I just found this out a few weeks ago, and have been working on a simple setup script for a few projects so admins can run the script interactively.

Anyway, so here it is:
# Prompts for y/n

:local prompt "Are you sure? [Y/N]:"
:local options "y,n"

# Array of ascii values and ascii characters
# The ascii values directly correspond to a single ascii character
# asciicharlower and asciicharupper are used for character conversions
:local asciicharlower ("a,b,c,d,e,f,g,h,i,j,k,l," . \
                                  "m,n,o,p,q,r,s,t,u,v,w,x,y,z")
:local asciicharupper ("A,B,C,D,E,F,G,H,I,J,K,L," . \
                                   "M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z")
:local asciichar ("0,1,2,3,4,5,6,7,8,9," . \
                         "a,b,c,d,e,f,g,h,i,j,k,l," . \
                         "m,n,o,p,q,r,s,t,u,v,w,x,y,z," . \
                         "A,B,C,D,E,F,G,H,I,J,K,L," . \
                         "M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z," . \
                         ".,/")
:local asciival {48;49;50;51;52;53;54;55;56;57; \
                       97;98;99;100;101;102;103;104;105;106;107;108; \
                       109;110;111;112;113;114;115;116;117;118;119;120;121;122; \
                       65;66;67;68;69;70;71;72;73;74;75;76; \
                       77;78;79;80;81;82;83;84;85;86;87;88;89;90; \
                       46;47}

:local key
:local findindex
:local validoption

:set key 0
:set validoption 0

# Prompt for input
:put ($prompt)

# Wait until valid option is entered
:while ($validoption = 0) do={

   :set key ([:terminal inkey])

# Convert numeric ascii value to ascii character
   :set findindex [:find [:toarray $asciival] $key]
   :if ([:len $findindex] > 0) do={
      :set key [:pick [:toarray $asciichar] $findindex]
   }


# If key is uppercase, convert it to lowercase
   :set findindex [:find [:toarray $asciicharupper] $key]
   :if ([:len $findindex] > 0) do={
      :set key [:pick [:toarray $asciicharlower] $findindex]
   }

# Check if key is a valid option
   :set findindex [:find [:toarray $options] $key]
   :if ([:len $findindex] > 0) do={
      :set validoption 1
   }

# end while validoption = 0
}


# Evaluate input
# At this point, key is converted to lower case
:if ($key = "y") do={
   :put ("You confirmed YES")
}
:if ($key = "n") do={
   :put ("You chose NO")
}
Basically, this prompts for a single character (y or n). If you type Y or N, it get's converted to lowercase. This way, during evaluation of the input, you only have to evaluate once (y or n).

Hope this helps. You could even set a global variable after input, and pass it to another script for execution.

Re: how to handle y/n response in .rsc script

Tue Apr 20, 2010 1:29 pm

wow thats a great script.

It looks as the script prompts user for yes/no.
Currently I just want to answer the yes/no that is presented.

Example .rsc file
> system routerboard upgrade
:delay 2
:put y 
Results
Opening script file test2.rsc

Script file loaded successfullyDo you really want to upgrade firmware? [y/n] 

The .rsc file has system routerboard upgrade command, and it halts me on the question. I want the script to answer yes. Can I use the :put command for the y?

RouterOS Script can't answer to prompt questions.

You could probably use telnet/ssh connection with something that waits for the prompt, then sends the 'Y' key over the connection.

I haven't done this, but have seen it mentioned a on the forums somewhere.

Prompt was removed when running commands from scripts for a very long time now.
When I run
/import some_script.rsc
I got prompt on my Windbox 6.38.7
[admin@MikroTik] > /import flash/reset.rsc 
Dangerous! Reset anyway? [y/N]: 
n
action cancelled


Script file loaded and executed successfully
and reset.rsc contains
/system reset-configuration
