Фильтрация вывода на терминал и запись в файл
У меня есть следующая команда: sudo evtest /dev/input/event3
Я фильтрую вывод, используя sudo evtest /dev/input/event3 | grep 'type 1', отлично работает
Я хочу записать вывод в файл, и пробовал несколько различных команд, например sudo evtest /dev/input/event3 | grep 'type 1' | tee ~/out.txt. Не работает Это означает, что я ничего не получаю в терминале, и создается пустой файл ...
Кроме того, при использовании вышеуказанной команды без grep (`sudo evtest / dev / input / event3> out.txt) запись в файл работает
Я не уверен, как объединить эти две команды, и не мог найти ничего подобного
EDIT 1
sudo evtest /dev/input/event3 | grep 'type 1' > out.txt, кажется, работает. Когда я изменяю его на sudo evtest /dev/input/event3 | grep 'type 1.*value 1' > out.txt, файл остается пустым. sudo evtest /dev/input/event3 | grep 'type 1.*value 1' работает, отображается только необходимый вывод

^C
Итак, как это сделать? (grep с 'type 1. * value 1', запись в файл и отображение в терминале)
