「mystring」をgrepすると、次の形式で数行が表示されます。

grep -B1 -A2 mystring myfile.log | grep -B1 -A2 mystring myfile.log | grep -B1 -A2 mystring myfile.log | grep "2009年6月4日" -A3

しかし、上記のタイムスタンプとともに「デルタポイント」のある行が必要な次の形式で行を取得したいと思います。 「ポストライン引数」（-A2）を（-A5）に増やすことはできますが、同じgrepコマンドで名前のある文字列を取得して複数回発生した場合に「増分点」を見逃さないようにするにはどうすればよいですか？ "私の検索文字列の文字列行または特定の時間範囲の行（2009年6月4日）

これを試してみてください。これがあなたに効果があるようです。

$ awk -v d="Jun 04 09" 'BEGIN { n=1;i=1;start=0;split(d,mon);extrahour=mon[1]" "mon[2]" "mon[3]+1;}

/mystring/ { if (i==1 && start == 1 ){ n=split(a,b,"\n");for (j=1;j<n;j++) print b[j];a="";  }

if (start == 1) { print "-----\n"l"\n"$0;n=2;i=1;next} }

/^Incremental/ { if (start==1) { print a"\n"$0;a="";n=1;i=0; }}

{ if( $0 ~ d )start=1; if ( $0 ~ mon[1] &&  ( $0 !~ d && $0 !~ extrahour ) ) {start=0;} 

  if ( start==1 ) {  l=$0; if (n==2) a=a"\n"$0  }

 } ' file | sed /^$/d
