Python + bash
Если вам часто требуется запускать shell команды из Python-кода, какой способ вы используете?
Самый низкоуровневый это функция os.system(), либо os.popen(). Рекомендованный способ это subprocess.call(). Но это всё еще достаточно неудобно.
Советую обратить своё внимание на очень крутую библиотеку sh.
Что она умеет?
🔸 удобный синтаксис вызова команд как функций
# os
import os
os.system("tar cvf demo.tar ~/")
# subprocess
import subprocess
subprocess.call(['tar', 'cvf', 'demo.tar', '~/'])
# sh
import sh
sh.tar('cvf', 'demo.tar', "~/")
🔸 простое создание функции-алиаса для длинной команды
fn = sh.lsof.bake('-i', '-P', '-n')
output = sh.grep(fn(), 'LISTEN')
в этом примере также задействован пайпинг
🔸 удобный вызов команд от sudo
with sh.contrib.sudo:
print(ls("/root"))
Такой запрос спросит пароль. Чтобы это работало нужно соответствующим способом настроить юзера.
А вот вариант с вводом пароля через код.
password = "secret"
sudo = sh.sudo.bake("-S", _in=password+"\n")
print(sudo.ls("/root"))
Это не все фишки. Больше интересных примеров смотрите в документации.

🇬🇧The Psychological Attack on the UK, Part 2 | UKColumn - 2021
If Bezmenov had been correct in just one or two of his predictions, then we might assume that coincidence was at work. In reality, he was correct in all of his predictions. Common sense therefore tells us that the plan he describes must be both real and effective. And that plan ultimately leads from 'Demoralisation' to 'Destabilisation', to 'Crisis' (Chaos) and then 'Normalisation' — so-called 'peace' (actually pacification) under a socialist/communist dictatorship of global scale.
In Part 2 as we tackle the key subversively targeted area of Security (covering the intelligence community, police and military), but first we address the demoralising and destructive plans detailed for Law and Order and Social Relations.
To recap, the following descriptive paragraph sets out the key warning within Story's highly detailed and meticulously researched book:

For the first time in a protest policing operation in the UK, live AI facial recognition will be used alongside aerial surveillance employing helicopters and drones, as well as armoured vehicles and large-scale specialist policing units deployed across the capital. Around 4.000 officers will be involved in the operation, with reinforcements from forces across England and Wales, as authorities reportedly prepare for "significant public order risks" across multiple protest routes.
