Re: [tcljava-user] '|' as a separator of distinct commands

[Ross, B. <Bil...@Ca...>]

I think I understand it better now.
You want a box to sit and listen for commands and then respond back to them.
Your problem is that the linux box intercepts the "|" symbol and doesn't pass it on.
I have not done anything like that.

I'm also using expect. Expect4j to be precise and i am also able to send and/or to receive the '|' through CLI on equipments.

I just want to reproduce those equipments behaviour on a linux box (that's i call a mock).
The aim is to test my application code against this box (this false device) to ensure non-regression testing.
You can understand i cannot neither test against operationnal equipments in the operationnal network nor have all my tests cases reproduced in a specific test plateform .
So i want to mock my tests cases on a easily programmable machine. A linux machine.

And this linux system cannot natively consider the '|' an argument of a command.

For instance in those equipments you can have the following line :

> cmd arg1 | arg3


where '|' is the second argument. Not a separator.


On a typical linux shell, the only thing i can do is :

> cmd1 arg 1 | cmd2 arg1

where  '|' is a separator between cmd1 and cmd1. Not an argument.

Hope i'm getting clearer.

Thx,

I am not sure what you are trying to accomplish.
I have used tcl with expect to communicate with Cisco devices.
My script runs on a linux box
I have been able to send the "|" character and capture and recognize it.
There are a few times where I struggled getting some characters to work.
I can send you some code if that is what you are trying to do.

Subject: [tcljava-user] '|' as a separator of distinct commands

Hello world,

Sorry if my topic is irrelevant considering this list.
In such case, you may gently tell me where this post would be more appropriate!

I'm trying to mock some network equipments (Cisco, Juniper, Whatever, ...) shell on on a linux shell.
My problem is the '|' character :
  - on most of those equipments, '|' is considered as an arg of a command
  - on a linux shell, '|' is a separator of distinct commands

I though tcl could help me to jump over this issue.
After i have installed tcl-8.4.13-4.el5.x86_64.rpm, I did some scripting through tclsh, tclshrc with no success.

By now, I'm still digging a full java solution trying to recreate a console from scratch based on jacl.
I've been playing with http://www.ensta-paristech.fr/~diam/tcl/online/Using_Tcl_in_Java-20010106.html
I did compile (except ConsoleThread.safeEvalCommand) and run it but i cannot figure out how insert my custom commands.

If any of you did face my need and/or this particular issue or found an alternative solution, i'd be glad to get some return on experience.

In one word, i'm afraid to face a dead-and problem soon.
And before i get completely stuck, i wonder if some of you guys could give me a track...

thanks.
