Cut specific logs #file #vi #cut

If you need to cut specific logs from the complete log of any application, here is a tip that will

be of help.

Open the log file in a vi editor and set the editor to display the line number:

vi server.log

:set nu

The above process will provide you the line numbers in the logs. You can then search for

the specific string and note down the line number (e.g., 550). Now, note down the last line

number by using Shift+G (e.g., 780)

sed -n 550,780p server.log > new.log

So the new only contains lines from 550 to 780.
