Как я могу сделать трассировку стека с помощью grep и regex?

У меня есть трассировка стека, подобная этой:

Как я могу получить вышеуказанный формат вывода (поиск всех строк ERROR с деталями)?

Похоже, этого должно быть достаточно, чтобы отфильтровать сообщения INFO из ввода: 

$ grep -v '[0-9] INFO ' file.in

Я добавил [0-9] и правильный интервал вокруг INFO , чтобы убедиться, что он не соответствует ни одной из строк, связанных с ERROR (в случае, если в ней появляется случайная строка с INFO там).

Если у вас есть несколько файлов журнала в каталоге: 

$ grep -v '[0-9] INFO ' *.log

где *. Log - шаблон имени файла, который соответствует файлам журнала.

Я столкнулся с точно такой же проблемой.

Хотя grepможет показывать строки контекста по флагу -A, но количество строк контекста фиксировано. Вместо этого вы можете попробовать awk.

Вот фрагмент, который я использовал ранее (https://gist.github.com/maoshuai/33113ac457aca7869171942c696f46d3), сохраненный как fullgrep.sh:

full_grep()
{
    # keyword to search
    local keyword=$1
    # mark the actual new line, in this job, it is always a date
    local newLinePattern="^[0-9]{2}\/[0-9]{2}\/[0-9]{2} [0-9]{2}:[0-9]{2}:[0-9]{2}"

    cat | awk  '
            BEGIN{
                isFound = "no"
            }

            # match lines with keyword
            {
                # if match print the line
                if($0~/'"$keyword"'/)
                {
                    print $0
                    isFound="yes"
                }
                # if new line begin, flush the flag
                else if($0~/'"$newLinePattern"'/) 
                {
                    isFound="no"
                }
                # if isFound, print continuely
                else if(isFound=="yes") 
                {
                    print $0
                }   
            }
            ' 
}


full_grep $@

Затем введите :cat test.log| fullgrep.sh ERROR, вы должны просто получить желаемый результат.
