I have created a runnable script to start my nodes like startnode1.sh with the following commands

geth --networkid 4321 --mine --datadir "~/iotproject/node1" --nodiscover --rpc --rpcport "8545" --port "30303" --rpccorsdomain "*" --nat "any" --rpcapi eth,web3,personal,net --unlock "0" --password ./password.sec --ipcpath "~/.ethereum/geth.ipc"

When run the command ./startnode1.sh iam getting the following error enter image description here
