The number that changed shells

Описание и применение

Декларатор, подсчитывающий строки, выдавал разные результаты в cmd.exe и bash из‑за обработки символа ^. После обновления он выполняется в обеих оболочках и требует согласия, обеспечивая стабильные счётчики.

Задача

A declarator tool produced inconsistent line counts when run in different shells (cmd.exe vs bash) due to shell‑specific handling of the caret (^) escape character.

Результат

After enforcing dual‑shell execution and agreement, the declarator consistently produced the same counts across environments, eliminating phantom matches caused by caret escaping.

Рабочий процесс

• 1. Execute the declarator command in cmd.exe. 2. Execute the same command in bash. 3. Compare the two integer results. 4. If the numbers match, accept the count and write it to disk. 5. If they differ, abort and report both numbers and the shell names.
• 6. Update the guard to reject any command that is silent in either shell.
• 7. Re‑run the acceptance test suite through both shells to confirm consistency.

Доказательства

The declarator had been told to run everything twice and demand the same integer; it did, and it got ninety‑two twice — because both runs used the same shell.

Источник

Every declared count runs in both shells — cmd.exe and bash — and the two must agree on the same integer before anything is written or pushed.
