extract it to a new folder - enter said folder

>bash ./start.sh

because a dumb developer put in a forwarding command that gives error with sh ^^^

>./diskcoin-cli getinfo
>./diskcoin-cli getblockcount
>./diskcoin-cli getpeerinfo

very interesting command - use data from getinfo / getblockcount and verify against getpeerinfo to see
- if you see more than 1 peer (hint that you could be blacklisted if only 1 or 0 peers)
- your height is the same as that of most peers (synced-height)
- check for hanging peers (have lower synced-height than others ....)

>./diskcoin-cli getnewaddress

once that all works without errors - copy the address-string into your miner's config - its your receiving address

then mine .. and wait for the surprises of wallet-forks, rewinds

see also https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_calls_list for a comprehensive list of most commands ... some dont work anymore since the bitcoin cash wallet used here is younger ...


small hint to the devs ... if you "testnet" .. why set "testnet": false in your wallet ? ROFL

EDIT

from Version 0713 onward .. the wallet includes a QT-driven application .. so if you have a "klickibunti" on your linux
just run ./diskcoin-qt &  and have fun
