上記の出力形式をどのように取得できますか（詳細情報を含むすべてのエラー行を見つける）？
答え1
INFO入力からメッセージをフィルタリングするだけで十分です。
$ grep -v '[0-9] INFO ' file.in
関連行が一致しないことを確認するために[0-9]正しい間隔を追加しました（ランダムな文字列がある場合）。INFOERRORINFO
ディレクトリに複数のログファイルがある場合：
$ grep -v '[0-9] INFO ' *.log
*.logログファイルと一致するファイル名パターンはどこにありますか？
答え2
私は同じ問題に直面しました。
フラグ-Aを介してコンテキスト行を表示できますが、grepコンテキスト行数は固定です。代わりに試してみてくださいawk。
以前使用したスニペットは次のとおりです（https://gist.github.com/maoshuai/33113ac457aca7869171942c696f46d3）、fullgrep.shとして保存します。
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 $@
次に、次のように入力すると、目的のcat test.log| fullgrep.sh ERROR結果が得られます。
