apache2: Как искать строку из apache2 журналов ошибок в определенном диапазоне времени?

Я создал простой сценарий, на основе предложенного ответа. Сценарий имеет пять входных переменных:

• $1 - дата от (представляют в виде строки от),
• $2 - дата к (представляют в виде строки к),
• $3 - файл журнала, полный путь и имя
• $4 - первая строка, которая будет искаться
• $5 - вторая строка, которая будет искаться

Содержание сценария:

#!/bin/bash

# Escape all special characters: "[", "]", ":", " ", "."
s1="$(echo $1 | sed -e 's/\[/\\\[/g' -e 's/\]/\\\]/g' -e 's/\:/\\\:/g' -e 's/\ /\\\ /g' -e 's/\./\\\./g')"
s2="$(echo $2 | sed -e 's/\[/\\\[/g' -e 's/\]/\\\]/g' -e 's/\:/\\\:/g' -e 's/\ /\\\ /g' -e 's/\./\\\./g')"
s3="$3"
s4="$(echo $4 | sed -e 's/\[/\\\[/g' -e 's/\]/\\\]/g' -e 's/\:/\\\:/g' -e 's/\ /\\\ /g' -e 's/\./\\\./g')"
s5="$(echo $5 | sed -e 's/\[/\\\[/g' -e 's/\]/\\\]/g' -e 's/\:/\\\:/g' -e 's/\ /\\\ /g' -e 's/\./\\\./g')"
[ ! -z "$s5" ] && s5=".*$s5"

# Crop the log file
sudo sed -n "/$s1/,/$s2/p" "$s3" | grep --color=always "$s4$s5"

Давайте назовем сценарий crop-log и поместите его в /usr/local/bin, таким образом это будет доступно как широкая система команд оболочки:

sudo touch /usr/local/bin/crop-log
sudo chmod +x /usr/local/bin/crop-log
sudo nano /usr/local/bin/crop-log

• Скопируйте содержание вышеупомянутого сценария и используйте в nano: Shift+Insert для вставки; Ctrl+O и Вводят, сохраняют; Ctrl+X для выхода.

Пример использования:
