Not sure why the test script is including command with arguments? The above echo command passed but random echo command fails? ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/f/fbd1da15c8b45f8d023e52e0719d3909fb4e0cfc.png) ---

I’ll take a look shortly. ---

Hi @R1zwan, I tried running your code against the previous stages, but it’s actually no longer passing the second stage **#CZ2 (Handle invalid commands)**. ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/f/ff3e6d64c05aefc10494877b202ee10861323002.png) Suggestions: 1. Use [our CLI](https://docs.codecrafters.io/cli/installation) to test against previous stages by running: ```auto codecrafters test --previous ``` 1. Focus on fixing the early stages first, as later stages depend on them. ---

> [@andy1li](#): > > `--previous` Hi Andy, Thanks for pointing out the issues in previous stages. I have fixed them. But the original issue remain as it is. the cli is printing the input command twice. ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/e/e3f1a42cacc85bcfe1a6db248dc17e6bca2c8e2d.png) ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/9/9786c983e59184fc77c573c2592332b1b8e562c2.png) ---

@R1zwan, this might be an issue on our own end. We’ll investigate it and keep you updated on any progress. ---

This bug is turning to be very interesting – the behavior is real, i.e. it isn’t a tester bug, the extra print is ACTUALLY happening. The bug only happens intermittently, and it is unique to C# programs. Other users are running into this too, but all of them are using C#. We came up with [a workaround](https://github.com/codecrafters-io/shell-tester/pull/93) that @ryan-gang will deploy shortly and test, and try to open a C# bug report once we’re able to work on reproducing this outside of our test framework. We’ll share the report here if we’re able to come up with a good minimal repo. In the 3 years we’ve been running CodeCrafters, this seems like the one case where “It’s never a compiler bug” is not going to be true 😃 ---
