I made a typo when I was creating and launching a single node test net.

I am trying to 'start again' but I don't know if I'm going about it the right way.

Here is what happens when I type nodeos --resync

How do I restart EOS so that I can try the tutorial again?

It looks like the nodeos process is still running judging by this output:

std::exception::what: bind: Address already in use

(your current nodeos process is trying to use the same address/port that's being used by the previous process that never exited)

Usually when this happens to me I find the process number with:

ps aux | grep nodeos

This will give an output like:

USERNAME+ 19218  1.3  0.2 1154228 45116 pts/0   S+   21:39   0:00 ./nodeos

Here the process id is 19218, you can kill it with:

sudo kill -9 19218

It looks like you're using a mac, so you can also use the activity monitor to kill the process if you can find it as well.

If that doesn't fix it, delete the data directory where the blocks are being stored (the location of this directory will change depending on which version of EOSIO and which OS you're running) and try again.

If all else fails, either rm -r the build directory and run ./eosio_build.sh again, or delete the entire eos directory and pull from git again.

The process is still running. You can kill the process by name using pkill:

pkill -9 nodeos

or as mentioned, you can also kill by process id:

ps | grep nodeos to list the pid followed by kill -9 <pid>
