Как импортировать песни из другого раздела в Rhythmbox?

Структура викторины, которую я придумал, размещена ниже, а также в моей учетной записи Github.

Как это выглядит довольно сложно, я лучше объясню, как это работает.

В сценарии версии Ubuntu и кодовые имена всех выпусков до сих пор хранятся в двух массивах , Затем переменные инициализируются вне цикла while, поэтому их можно при необходимости увеличивать в цикле с использованием нотации C style (( var++ )).

Затем я создаю еще один массив для номеров вопросов, в этом случае для 19 вопросов я должен включить 0 - 18 включительно:

questions_order=(15 4 1 10 8 3 13 0 11 16 2 7 5 17 6 9 14 18 12)

, а затем перетасовать его с помощью shuf и создать новый массив и использовать его для этого конкретного запуска скрипта:

Это должно быть сделано вне цикла, так как я хочу, чтобы он выполнялся один раз.

Короче говоря, цикл теперь выполняется до тех пор, пока текущее количество вопросов не будет равным к переменной "${target_questions}", а затем даны результаты.

Когда пользователь дает ответ на вопрос, он будет интерпретироваться различными условиями в инструкции case. Не ответы (пробелы), неправильные ответы, правильные ответы и проходы обнаружены и получены ответы, а все переменные все увеличиваются (например, для неправильного ответа, (( wrong++ ))).

Когда последний на вопрос был дан ответ, производительность пользователя оценивается там, где ретранслируется количество правильных, неправильных ответов и пропусков (если есть), и дается время.

Это краткое объяснение, но сценарий сам имеет различные комментарии, которые должны сделать работу понятной (ish)! Он может быть адаптирован для любого другого викторины, скажем, в столицах и странах.

Когда вы скопировали скрипт в файл, сделайте его исполняемым (chmod u+x) и запустите его с помощью ./scriptname или поместите его в папку ~/bin и назовите его по имени, как и любой другой (f12).
