I’ve tried copy pasting a solution from code example for sanity check, but even with passed solution I get following error when I git push: ```auto remote: remote: [compile] Moved ./.codecrafters/run.sh → ./your_program.sh remote: [compile] Compilation successful. remote: remote: Debug = true remote: remote: [tester::#IP1] Running tests for Stage #IP1 (Run a program) remote: [tester::#IP1] [setup] export PATH=/tmp/baz:$PATH remote: [tester::#IP1] [setup] Available executables: remote: [tester::#IP1] [setup] - custom_exe_3223 remote: [tester::#IP1] Running ./your_program.sh remote: [your-program] $ custom_exe_3223 Maria remote: [your-program] custom_exe_3223: command not found remote: [tester::#IP1] Output does not match expected value. remote: [tester::#IP1] Expected: "Program was passed 2 args (including program name)." remote: [tester::#IP1] Received: "custom_exe_3223: command not found" remote: [your-program] $ remote: [tester::#IP1] Assertion failed. remote: [tester::#IP1] Test failed remote: remote: Try our CLI to run tests faster without Git: https://codecrafters.io/cli remote: remote: View our article on debugging test failures: https://codecrafters.io/debug remote: To https://git.codecrafters.io/97c45f09a2edc441 6d619bf..683fa4e master -> master ``` ---

Hi @microwavestine, could you [upload your code to GitHub](https://docs.codecrafters.io/features/publish-to-github) and share the link? It will be much easier to debug if I can run it directly. ---

I’ve published it here [https://github.com/microwavestine/codecrafters-shell-python](https://github.com/microwavestine/codecrafters-shell-python) I’ve also tried the following code (will delete later): ```auto import sys import os def find_in_path(param): path = os.environ['PATH'] print("Path: " + path) print(f"Param: {param}") for directory in path.split(":"): for (dirpath, dirnames, filenames) in os.walk(directory): if param in filenames: return f"{dirpath}/{param}" return None def main(): while True: sys.stdout.write("$ ") sys.stdout.flush() # Wait for user input command = input() match command.split(" "): case ["exit", "0"]: exit(0) case ["echo", *cmd]: print(" ".join(cmd)) case ["type", *cmd]: match cmd: case ["echo" | "exit" | "type"]: print(f"${cmd[0]} is a shell builtin") case _: location = find_in_path(cmd[0]) if location: print(f"${cmd[0]} is {location}") else: print(f"${" ".join(cmd)} not found") case _: if os.path.isfile(command.split(" ")[0]): os.system(command) else: print(f"{command}: command not found") if __name__ == " __main__": main() ``` ---

Hi @microwavestine, the bug is here: ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/4/4e4d48cfa37cd94660d0692411a4beb81438a492.png) It does not work because `os.path.isfile` tests whether a **path** is a regular file, so you need to pass in a **path** rather than `command.split(" ")[0]`. ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/f/fc4e6b845b1ec6f97eb638d0b18aa01258f17f98.png) For example, try something like this instead: ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/e/e6e25b6cdada4a4822db65cc1723fc685068ef56.png) ---

I found a similar issue here, [(Rust) "Build your own shell" - Stage Run a program #IP1 always fails despite working before - #3 by omagdy7](https://forum.codecrafters.io/t/rust-build-your-own-shell-stage-run-a-program-ip1-always-fails-despite-working-before/3507/3) And found a hint from this [repo](https://github.com/nobleknightt/codecrafters-shell-python/blob/master/app/main.py) to solve it 😅 ---
