    codex
    It appears that commands to list or search files in the workspace are not working properly.
     Could you please confirm if you have uploaded or cloned the codebase here? Or if you      
    provide me with some files or folder names, I can try to analyze them to explain the       
    codebase to you.
user
hello.html

    command

    $ head -40 hello.html

    command.stdout (code: 1, duration: 0s)

    Error: spawn head ENOENT

    codex
    It seems basic shell commands are not working properly here. Could you please upload or    
    paste the content of the file hello.html so I can analyze it and explain the codebase to   
    you?
