README_old.md disappeared after first execution of ls command when implementing the bash tool #oq5

I’m stuck on Stage #OQ5 for the claude-code challenge.

I’ve tried to use env::current_dir() to get the working directory.

And I found the files when using ls command, but when I tried to delete the README_old.md, the file disappeared.

Here are my logs:

[tester::#OQ5] $ ./your_program.sh -p 'List project files using ls and delete the old readme file.'

[your_program] 
[your_program] The project files include:
[your_program] - **README.md** - Current readme file

[your_program] - **app** - Application directory
[your_program] 
[your_program] The old readme file (`README_old.md`) has been successfully deleted from the project.

And here’s a snippet of my code:

fn execute_bash(id: &str, arguments: &str) -> Result<Value, Box<dyn Error>> {
    eprintln!("Bash: id: {}, arguments: {}", id, arguments);
    if let Ok(arguments) = from_str::<Value>(arguments)
        && let Some(command) = arguments["command"].as_str()
    {
        let cur_dir = fs::canonicalize(env::current_dir()?)?;
        eprintln!("Bash: command: {}, cur_dir: {:?}", command, cur_dir);

        let result = Command::new(command).current_dir(cur_dir).output();
        match result {
            Err(error) => {
                eprintln!("Bash: command error:\n{}", error);

                Ok(json!({
                "role": "tool",
                "tool_call_id": id,
                "content": error.to_string()
                }))
            }

            Ok(output) => {
                eprintln!("Bash: success {}", output.status.success());
                let content = String::from_utf8(if output.status.success() {
                    output.stdout
                } else {
                    output.stderr
                })?;
                eprintln!("Bash: content:\n{}", content);

                Ok(json!({
                "role": "tool",
                "tool_call_id": id,
                "content": content
                }))
            }
        }
    } else {
        eprintln!("Bash: arguments error");
        Err("Invalid arguments".into())
    }
}

Hey @OnTheEasiestWay, the bug is on this line:

Command::new(command) treats the entire string as a single executable name. It doesn’t invoke a shell or split the command into arguments.

Instead, run it through a shell, for example:

let result = Command::new("sh")
            .arg("-c")
            .arg(command)
            .current_dir(cur_dir)
            .output();

This lets the shell parse and execute the command string as expected.

Thank you for your prompt response. It works like a charm now — great challenge!
