複製從正則表達式文件開始到文件結尾的文件內容

Question

我想複製從文件（搜索到的文字/行）開始的文件內容到文件末尾。

舉例： 文件1：

this is a sample text for file1 in PA 
this is a sample text for file1 in CA 
this is a sample text for file1 in CT 
this is a sample text for file1 in IL 
this is a sample text for file1 in MI 
end of the file. 

我要複製的內容從具有「CT」，直到文件的最後一行到file2。 輸出： 文件2

this is a sample text for file1 in CT 
this is a sample text for file1 in IL 
this is a sample text for file1 in MI 
end of the file. 

Answer 1

您可以使用sed：

sed -n '/searchtext/,$p' file1 > file2 

或awk：

awk '/searchtext/ {flag=1} flag;' file1 > file2 

Answer 2

awk '{if($0~/CT/)p=1;if(p)print}' your_file
