Your code is correct and works here as you described it should. So I assume the variable $used_net never is set to the correct "testnet" value.
Check the variable value directly before the shown command.
Another variant to run it:
Ok, I'll try that later today.
You want to explain how bash processes 2 variable atributions within the same line of code? Probably following some rule like left to right or right to left. But what is the return value of a successeful variable attribution (which I think will be the value assigned to 'btc_opt') in case of 'test' go false?
I couldn't find an existing thread that addressed this question, so hopefully this isn't redundant with anything previously posted. Here goes:

scope
scope(n) [incr Tcl] scope(n)
__________________________________________________________________________________________________________________________________________________NAME
scope - capture the namespace context for a variable
SYNOPSIS
itcl::scope name
_________________________________________________________________DESCRIPTION
Creates a scoped value for the specified name, which must be a variable name. If the name is an instance variable, then the scope command
returns a string of the following form:
@itcl object varName
This is recognized in any context as an instance variable belonging to object. So with itcl3.0 and beyond, it is possible to use instance
variables in conjunction with widgets. For example, if you have an object with a private variable x, and you can use x in conjunction with
the -textvariable option of an entry widget. Before itcl3.0, only common variables could be used in this manner.
If the name is not an instance variable, then it must be a common variable or a global variable. In that case, the scope command returns
the fully qualified name of the variable, e.g., ::foo::bar::x.
If the name is not recognized as a variable, the scope command returns an error.
Ordinary variable names refer to variables in the global namespace. A scoped value captures a variable name together with its namespace
context in a way that allows it to be referenced properly later. It is needed, for example, to wrap up variable names when a Tk widget is
used within a namespace:
namespace foo {
private variable mode 1
radiobutton .rb1 -text "Mode #1" -variable [scope mode] -value 1
pack .rb1
radiobutton .rb2 -text "Mode #2" -variable [scope mode] -value 2
pack .rb2
}
Radiobuttons .rb1 and .rb2 interact via the variable "mode" contained in the namespace "foo". The scope command guarantees this by return-
ing the fully qualified variable name ::foo::mode.
You should never use the @itcl syntax directly. For example, it is a bad idea to write code like this:
set {@itcl ::fred x} 3
puts "value = ${@itcl ::fred x}"
Instead, you should always use the scope command to generate the variable name dynamically. Then, you can pass that name to a widget or to
any other bit of code in your program.
