А знаете ли вы, что в Bash есть особая переменная "$_" ? Из описания можно узнать, что в переменную "$_" помещается последний аргумент последней команды. Что-то знакомое? Конечно, в Python есть примерно тоже самое. Мы знаем, что дата первого релиза Bash (8 июня 1989) несколько раньше чем первый релиз Python (20 февраля 1991). Если учесть, что по задумке автора Python это агрегация самых успешных практик отовсюду, можно ли сказать что именно эта фишка к нему пришла из Bash? Ни подтверждения ни опровержения я пока не нашел. Давайте просто считать это совпадением 😉 А как это может быть полезно в Bash? Приведу простой пример, который оценят те, кто часто работает в терминале. Допустим, нам надо создать директорию и зайти в неё. Что обычно делаем? :~$ mkdir foldername :~$ cd foldername :~/foldername$ Как это сделать в одну команду? :~$ mkdir foldername && cd foldername :~/foldername$ Уже лучше, но хочется короче, без повторов. Вот тут и пригодится наша переменная. Напомню, что в неё сохраняется последний аргумент предыдущей команды. :~$ mkdir foldername && cd $_ :~/foldername$ _________________ PS. Символы "&&"" разделяют команды и означают, что требуется выполнить вторую команду только если первая завершилась успешно. #linux#tricks

Trump Establishes Strategic Bitcoin Reserve Former President Trump has signed an order to create a strategic Bitcoin reserve in the U.S., based on approximately 200,000 BTC confiscated by the government. This reserve will serve as a savings asset, not intended for sale, acting as a digital Fort Knox. Meanwhile, analysts indicate that governments may follow the U.S. lead, reducing the likelihood of Bitcoin bans from regulators. Post-announcement, Bitcoin saw a price drop from $91,000 to $85,000 but has since recovered to $88,000. No altcoins are currently included in the reserve plans.
