打印僅僅是從開始直至到終點

例子：

Started at Mon Nov 25 14:30:02 ALMT 2013 
Load average for db1 is 10 which is less than 100 
Load average for db2 is 3 which is less than 100 
Load average for db3 is 6 which is less than 100 
Load average for db4 is 5 which is less than 100 
Load average for db5 is 5 which is less than 100 
Mon Nov 25                     page 
some other data 
some other data 
some other data

預計：

Started at Mon Nov 25 14:30:02 ALMT 2013 
Load average for db1 is 10 which is less than 100 
Load average for db2 is 3 which is less than 100 
Load average for db3 is 6 which is less than 100 
Load average for db4 is 5 which is less than 100 
Load average for db5 is 5 which is less than 100 
Mon Nov 25                     page

我試試那個：

perl -0777 -lpe 's|Started .*? page||xsg' 1

但是刪除了我想打印的整個區域。

犯錯我沒有看到任何終點。 – fedorqui

只是滾動到有正確的「開始在...」和完成是「25頁」 –

所以你記錄的「結束」是「開始」行日期，後跟字符串「頁」？在「頁面」之前有大量的空白？你必須具體，因爲我們無法讀懂你的想法：你必須告訴我們你需要什麼。 – TLP

或用sed。但要注意的是，如果遇到「啓動」標籤，但不是「結束」，將打印一切從開始標記文件的末尾

sed -n '/^Started/, /page/p' file

嘗試以下操作：

$ perl -0777 -lpe 's|.*(Started .*? page).*|$1|xsg' 1

類似的東西可以使它：

$ awk '/^Started/ {p=1} p; /page$/ {p=0}' file 
Started at Mon Nov 25 14:30:02 ALMT 2013 
Load average for db1 is 10 which is less than 100 
Load average for db2 is 3 which is less than 100 
Load average for db3 is 6 which is less than 100 
Load average for db4 is 5 which is less than 100 
Load average for db5 is 5 which is less than 100 
Mon Nov 25                     page

/^Started/ {p=1}當它發現開始「入門」的字符串，則標誌p設爲1.
p打印的情況下的線標誌p是真實的。
/page$/ {p=0}時，它會發現「頁」結尾的字符串，則標誌p設置爲0

另外，（thanks 1_CR）：

awk '/^Started/,/page$/' file

奇怪是不是我的控制檯上工作，只是打印所有輸出：一個符合「開始」，並以「頁」一行結束開始：/ –

檢查，如果你的樣品輸入下面的比賽。 – fedorqui

'awk'/^Started /，/ page $ /'file'應該也能正常工作 – iruvar

perl -0777 -ne 'print /(Started .*? page)/xsg' 1
