I found this bug and used gptme to give a summary at the end. Please let me know if this is a good way to report bugs and if there is anything I can do to improve on the reporting process.

Thanks

User: what does a red D mean in the htop command in status colum
Assistant: The `D` status in the `htop` command output stands for "Disk Sleep". It means that the process is in an uninterruptible sleep state. This is usually caused by the process waiting for an I/O operation to complete. 

In other words, the process is waiting for data that isn't in memory to be loaded from disk into memory. This could be due to a slow disk or a large amount of data being read. 

It's important to note that a process in `D` state cannot be interrupted or killed until it comes out of this state, even by signals like `SIGKILL` or `SIGSTOP` that normally have the power to terminate or pause any process.                                                                                                                                  User: how do we make sure that process is not dead?
Assistant: To ensure that a process is not dead, you can use the `ps` command with the process ID (PID). The `ps` command provides information about the currently running processes, including their PIDs.

Here's how you can use it:

```bash
ps -p <PID>
```

$ ps -p <PID>

bashlex.errors.ParsingError: unexpected token '\n' (position 11)

Assistant: The error message you're seeing is a `bashlex.errors.ParsingError`, which is raised when the `bashlex` library encounters a token it doesn't expect while parsing a bash script. In this case, the unexpected token is a newline character (`'\n'`).

This error is occurring in the `gptme` tool, which is a command-line interface (CLI) tool that uses the `bashlex` library to parse and execute bash commands. It seems that `gptme` is trying to parse a bash command, but it's encountering a newline character where it doesn't expect one, causing the parsing to fail.

To resolve this issue, you would need to identify the bash command that's causing the error and correct it. The error message doesn't provide enough information to identify the exact command that's causing the problem, but it's likely that there's a syntax error in the command.

If you're writing a bash script, make sure that all commands are correctly formatted and that there are no unexpected newline characters. If you're entering commands directly into the `gptme` tool, make sure that you're following the correct syntax for each command.

The error is caused by an unexpected newline character (`'\n'`). This suggests that there's a syntax error in the bash command being parsed, possibly an unexpected newline character in a place where it shouldn't be. The exact command causing the error isn't specified in the traceback. The solution would involve identifying and correcting the problematic bash command.

This happens when it tries to run a command with <PID> since it then expects an output file to pipe to.

I should add a test case for this, and make sure it gives an appropriate error that we catch (along with any other tool-related exceptions) and return to the conversation so the LLM can see the oopsie.

I also think gptme needs a better way to let the LLM communicate "this is just an example, we do not mean to run it".

I fixed so that the error is handled more gracefully in becab4d

Tracking the more fundamental UX issue about examples vs runnable code in #67

Thanks for reporting!
