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.
