Fine as a personal exercise, of course. The inability to download modules seems sadistic to me, though.
And given the adage "Never create a rule you can't enforce", I wonder how they enforce it - have to be pretty hardcore to make sure that stuff doesn't get imported via USB or tethering off a cellphone. (Or more correctly, I know how they do those sort of things if you're a spook agency or doing classified research - how do you make it palatable to employees in corporate sites?) ------------------------------------------------- It's not corporate and believe me, they enforce it... ;-) scott

Yeah... just download RANCID and check the command line options. Expect is mainly of historical interest, and the code already exists in several forms, so no need to completely re-invent the wheel (as a square) here. I call shenanigans about the avoidance of Perl modules. No real-world system has such constraints. Besides, Expect itself is a module / extension of the Tcl language and requires the use of dynamically-loaded extension libraries for pattern matching and various functions, so using Expect would break the "No modules rule". If you're not allowed the use of modules, then your implementation option is pretty much to write in something that compiles to straight machine language. -- -JH

In a follow up he stated that wasn't allowed either.

As someone who administers systems with such constraints, allow me to say that you are incorrect in your assertion.
