sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" ~/.mineplex-chain/config/app.toml && \
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" ~/.mineplex-chain/config/app.toml
```

### Create service

```
sudo tee /etc/systemd/system/crossfid.service > /dev/null <<EOF
[Unit]
Description=Crossfi node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.mineplex-chain
ExecStart=$(which crossfid) start --home $HOME/.mineplex-chain
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF
