On stage #PN5, if a program is implemented so that it says `exit: command not found` when an exit command is issued, the tester logs say this:

```auto
[tester::#PN5] Running tests for Stage #PN5 (The exit builtin)
[tester::#PN5] Running ./your_program.sh
[your-program] $ invalid_orange_command
[your-program] invalid_orange_command: command not found
[tester::#PN5] ✓ Received command not found message
[your-program] $ exit 0
[tester::#PN5] Error reading output: condition not met
[tester::#PN5] Test failed (try setting 'debug: true' in your codecrafters.yml to see more details)

```

Here’s what I get when running my program locally and executing the same command:

 ![Screenshot 2025-03-25 at 18.35.13](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/6/6b726a39619896ca9b97c3eba9e1b75c20828890.png)

Here’s a snippet of my code:

```rust
use std::io::{self, Write};

fn main() {
    loop {
        print!("$ ");
        io::stdout().flush().unwrap();

        let mut input = String::new();
        io::stdin().read_line(&mut input).unwrap();
        input = input.trim().to_string();

        let command_with_args = input.split_whitespace().collect::<Vec<&str>>();
        let command = command_with_args[0];
        let args = command_with_args[1..].to_vec();

        if input == "exit" {
            break;
        }

        println!("{}: command not found", command);
    }
}

```

The fix is simple (change `input == "exit"` to `command == "exit"`), but the tester message is pretty confusing. Instead of “condition not met”, I’d expect:

- (a) a message indicating that the program was expected to exit but it didn’t.
- (b) the rest of my program’s output, i.e. the second prompt to be printed so that I know what it did wrong

@rohitpaulk  
Replace the line \< if input == “exit” \> with \< if input == “exit 0”

It will work
