Нужно установить cron для случайных интервалов с iMacros

Я пытаюсь узнать о cron для iMacros, но я не знаю, где искать. Гугл не помог.

В основном у меня есть сценарий, который я написал, серия команд, например:

Line 1 Line 2 Line 3 

и т.п.

Что я хочу сделать, так это запускать, скажем, 10 строк каждые 5-10 минут (произвольно выбирать время в течение 5 и 10 минут), а между каждой строкой должен быть интервал времени, скажем, от 2 до 5 секунд между (случайным образом определите время в течение 2 и 5 секунд).

Я новичок в iMacros и не знаю, с чего начать изучение их языка сценариев. Однако я смог написать несколько действительно хороших сценариев, которые работают очень хорошо, но я не знаю, как написать для него cron.

Короче говоря, это должно выглядеть примерно так (я заменил код на описание нужного мне cron; «Строка 1» - просто заполнитель кода, на котором я хочу запустить cron):

Line 1 [run cron, between 2 and 5 seconds before executing next line] Line 2 [run cron, between 2 and 5 seconds before executing next line] Line 3 [run cron, between 2 and 5 seconds before executing next line] Line 4 [run cron, between 2 and 5 seconds before executing next line] Line 5 [run cron, between 2 and 5 seconds before executing next line] Line 6 [run cron, between 2 and 5 seconds before executing next line] Line 7 [run cron, between 2 and 5 seconds before executing next line] Line 8 [run cron, between 2 and 5 seconds before executing next line] Line 9 [run cron, between 2 and 5 seconds before executing next line] Line 10 [run cron, between 2 and 5 seconds before executing next line] [run cron, between 5 and 10 minutes before executing next line] Line 11 [run cron, between 2 and 5 seconds before executing next line] Line 12 [run cron, between 2 and 5 seconds before executing next line] Line 13 [run cron, between 2 and 5 seconds before executing next line] Line 14 [run cron, between 2 and 5 seconds before executing next line] Line 15 [run cron, between 2 and 5 seconds before executing next line] Line 16 [run cron, between 2 and 5 seconds before executing next line] Line 17 [run cron, between 2 and 5 seconds before executing next line] Line 18 [run cron, between 2 and 5 seconds before executing next line] Line 19 [run cron, between 2 and 5 seconds before executing next line] Line 20 [run cron, between 2 and 5 seconds before executing next line] [run cron, between 5 and 10 minutes before executing next line] Line 21 [run cron, between 2 and 5 seconds before executing next line] Line 22 [run cron, between 2 and 5 seconds before executing next line] Line 23 [run cron, between 2 and 5 seconds before executing next line] Line 24 [run cron, between 2 and 5 seconds before executing next line] Line 25 [run cron, between 2 and 5 seconds before executing next line] Line 26 [run cron, between 2 and 5 seconds before executing next line] Line 27 [run cron, between 2 and 5 seconds before executing next line] Line 28 [run cron, between 2 and 5 seconds before executing next line] Line 29 [run cron, between 2 and 5 seconds before executing next line] Line 30 [run cron, between 2 and 5 seconds before executing next line] [run cron, between 5 and 10 minutes before executing next line] Line 31 [run cron, between 2 and 5 seconds before executing next line] 

и т.п.

Было бы еще лучше, если бы у меня был сценарий, похожий на следующий, но я бы не знал, с чего начать:

[run sets of 10 lines, consecutively increasing number x, "Line x" x+1, waiting between 2 and 5 seconds before executing each line; then after each set of 10, pause for randomly generated interval of between 5 and 10 minutes before executing next set; repeat]
