Check the variable value directly before the shown command.

Another variant to run it:

Code:
[ "$used_net" == "testnet" ] && btcopt="-testnet" || btcopt=
btc_dec=$(bitcoin-cli $btcopt getbalance)

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?
