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.

A Guide To Food Storage©Utah State University FEMA, the Federal Emergency Management Agency, advocates disaster preparedness. They advise people to be informed, make a plan, and prepare an emergency kit. A major part of that emergency kit is food and water for you and your family. But, what types of food should you store? How much food should you store? How will you cook it? Does it need to be refrigerated? How much water needs to be stored and how? Will these foods go bad during storage? Can my family or I become sick if we store these foods incorrectly? Can I throw these foods in my car in case I am forced to evacuate my home? These are all questions that you need to consider in both your planning and preparation stages. #household#prepper#foods

https://permacomputing.net/ 数字领域的朴门实践正在芬兰萌芽! New to permacomputing? Permacomputing is a more sustainable approach to computer and network technology inspired by permaculture. Permacomputing is both a concept and a community of practice oriented around issues of resilience and regenerativity in digital technology. In a time where computing epitomizes industrial waste, permacomputing encourages a more sustainable approach, maximizing hardware lifespans, minimizing energy use and focussing on the use of already available computational resources. We do this because humans are part of nature and technology is an extension of humans, and we acknowledge that technology has been used to harm nature. We want to find out how we can practice good relations with the Earth by learning from ecological systems to leverage and re-center existing technologies and practices. We are also interested in investigating what a permacomputing way of life could be, and what sort of transformative computational culture and aesthetics it could bring forward. If you want to know more, please start reading about what is permacomputing in essence, and then dive into its principles. Wiki Started in May 2022, the permacomputing wiki is where we maintain a set of principles, collectively document practical perspectives and interpretations of these principles, and offer more speculative reflections on permacomputing. The wiki is still at a very early stage of development, we are frequently working on it. This main page of the wiki is an index to the various topics covered. See "about" for a more detailed discussion about the wiki itself. #致呼吸不畅的数字生活#DIY#prepper
