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

🌎 The male seahorse is the only animal where the male becomes pregnant, carrying fertilized eggs in a special pouch until they hatch. Seahorses can give birth to hundreds of fully formed young at a time—up to 2,000 in a single brood. ✨ #adaptation⚡#animals⚡#ocean 👉subscribe Interesting Planet 👉more Channels
