#xcode #md5 #checksum
#xcode #md5 #контрольная сумма
Вопрос:
В программном обеспечении есть способ проверить, правильно ли оно загружено, я полагаю, что это называется дайджестом MD5 или имеет какое-то отношение к MD5 или контрольным суммам; я не могу точно вспомнить, как это называется.
Существует ли такой инструмент или услуга в отношении Xcode? И если да, есть ли ссылка, по которой я могу перейти, чтобы узнать больше?
Мне интересно, правильно ли загрузился загружаемый мной Xcode, полностью или нет; и это может быть причиной того, что мой Xcode ничего не архивирует в отношении профилей специальной подготовки?
Если есть такой инструмент, пожалуйста, отправьте ссылку.
Спасибо
Ответ №1:
Xcode загружается в виде образа диска. Образы дисков уже имеют встроенную контрольную сумму, поэтому, если образ диска монтируется на вашем рабочем столе, вы знаете, что это правильно.
Комментарии:
1. О, хорошо. Я думаю, что тогда это не должно быть так.
Ответ №2:
Вот метод, позволяющий использовать md5sum для каждого файла внутри Install Xcode.app , а затем выводить md5 в файл, затем проверять каждый md5 с помощью md5sum -c :
[ 15:11 Jonathan@MacBookPro /Applications ]$ find /Applications/Install Xcode.app/ -type f -exec md5sum {} >> ~/xcode.md5 ;
[ 15:13 Jonathan@MacBookPro /Applications ]$ md5sum -c ~/xcode.md5

1. Попробовал вашу идею, но я получаю сообщение «найти: md5sum: нет такого файла или каталога». Я попробовал md5sum, и он говорит «md5sum: команда не найдена». Я попробовал «установить порт md5sum», но там написано «Порт md5sum не найден»: (
2.
md5sumсуществовал в более старых версиях OS X, но он не существует в 10.7, и я не уверен, что он даже существовал в 10.6.3. @Kevin Моему macbook pro 2 недели, он поставляется с версией 10.7, и на нем уже установлен md5sum. Странно.
4. @chown: Вы выполняли миграцию с другого компьютера? Возможно, у вас был установлен md5sum в качестве стороннего инструмента?
5. @KevinBallard О да, я предполагаю, что я скопировал некоторые вещи из моего старого MacBookAir, я не помню, чтобы копировал md5sum, но поскольку он находится в
/usr/local/bin/md5sum, я должен иметь. Хороший звонок!
