To grep 10 lines after a string in a txt file.

suman82 · #1 (**permalink**) 12-06-2008

Hi All,
I am trying to pull 10 lines from a file after some particular string. Please help me in doing so.

Example;
Let us take a file.

Test_file_log.txt

Test_file_log contents:

request_id = 11191
Test data related to 11122
test date
trst data
test data

request_id = 11123
test data related to 11123
test_data
test_data

request_id = 11234
test data related to 11234
test_data
test_data

Our requirment: Need to get the data for the given request_id and send it over to other file.

here request_id is dynamic. We pass the request_id value.

Let us suppose we need the data for
v_request_id = 11123

grep "request_id = v_request_id" and also 10 lines after this string. Then send this information to other file.

>request_id_data.txt

Finally Request_id_data.txt should have the log of only the given request_id

Please help me in coding the above. I am searching in all forums but cannot able to get the info. We are trying to do this from past 2 months.

Thanks in advance

Regards,
Suman.
