linux - copy contents of a file starting from regex word to end of the file

Question

I want to copy a content of a file starting from word (searched word/line) to the end of the file.

Example: File1:

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.

I want to copy contents to file2 from line that has "CT" till the end of the file. Output : File2

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
