I have a problem when I run codecrafters test I get this error

[tester::#MG5] Running tests for Stage #MG5 (The type builtin: executable files)
[tester::#MG5] [setup] export PATH=/tmp/bar:$PATH
[tester::#MG5] [setup] export PATH=/tmp/foo:$PATH
[tester::#MG5] [setup] Available executables:
[tester::#MG5] [setup] - my_exe
[tester::#MG5] Running ./your_program.sh
[tester::#MG5] Expected prompt ("$ ") but received ""
[tester::#MG5] Assertion failed.
[tester::#MG5] Test failed

and it’s working fine on my pc, i don’t know where is the problem and I print the prompt at the beginning of the code

  // extract environment paths
  char *fullPaths = getenv("PATH");
  pathCounter = extractPaths(fullPaths, environmentPaths);

  while(1) {
    // Uncomment this block to pass the first stage
    printf("$ ");

    // Wait for user input
    fgets(input, sizeof(input), stdin);
...

Hey @MostafaEdrees11, could you upload your code to GitHub and share the link? It will be much easier to debug if I can run it directly.

Hey @andy1li
This is the link for the repository

@MostafaEdrees11 I added a few logs:

Notice that the after loop flag is never printed:

This means the code is stuck inside the loop and never exits.

Since the outer loop is straightforward enough, the issue must stem from the inner loop:

Turns out the inner loop needs an out-of-bounds check as well to avoid running indefinitely.

Let me know if you’d like further clarification!

Thank you @andy1li very much :heart::heart:, It’s works
The problem in the infinite loop as you mentioned
