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.

Okay, here's an analysis of the ETH liquidation map suitable for Twitter, formatted in Markdown:
🚨#ETH Liquidation Map Analysis 🚨
Here's what the liquidation map tells us about potential price action. 👇
1️⃣Main Liquidation Zones: The BIGGEST liquidation cluster is concentrated AROUND & BELOW the current price (~$2626). Smaller clusters exist further below, around the 2500 to 2600 levels, while Long liquidations reside further above, between 2690 and 2712.
2️⃣Key Price Levels to Watch:
* Potential Support (Liquidation Zone): $2500-$2600 acts as strong support and bounce zone.
* Danger zone: 2626, current price is the biggest Liquidation cluster
* Resistance (Liquidation Zone): $2690 - $2712; push beyond here could trigger more long liquidations.
3️⃣Longs vs. Shorts: The image shows FAR more long liquidations than short liquidations which have already been cleared out. A HUGE cluster of longs is currently sitting under the current price, which can be liquidated.
4️⃣Potential Price Movements: Given the concentration of long liquidations below the current price, a move *DOWN* to trigger those liquidations seems more probable. 📉 Expect volatility around these liquidation zones!
5️⃣Key Takeaways for Traders:
* Be cautious of longing: Lots of longs sitting right at the current price could be liquidated.
* Anticipate volatility: Large liquidations can fuel price swings. Manage your risk accordingly!
* Watch key levels: $2500-$2600 as a potential support/bounce area and $2690-$2712 as potential resistance.
