Я пробовал что-то вроде:
grep "May ,25" $1
где $1 - имя файла, которое вводит пользователь. В принципе, предполагается, что он должен найти строки, содержащие дату 25 мая, но он не выводит абсолютно ничего. Я точно знаю, что есть строки, содержащие дату 25 мая.
Я также попробовал следующее, но это все еще не работает:
grep "\"May\" ,25" $1
Что я делаю неправильно?

Цитаты тоже символы - в ваших файлах нет May, 25 , там есть «May», 25 . Итак,
grep '"May",25' "$1"
или
grep "\"May\",25" "$1"
(но не grep "\" May \ ", 25" "$ 1" - пробелы также являются символами).
Или вы можете использовать инструмент, поддерживающий CSV, который понимает цитирование CSV:
mlr --csv filter 'Month == "May" && Day == 25'
csvgrep -c Month -m May "$1" | csvgrep -c Day -m 25
