Adding additional newline between each line

I am analyzing log files from my server(particular few lines from there). But those lines are having around 1000 to 2000 characters in length. Here is an example how the lines are coming out with `grep` and `less` with following command. ``` tail -n 1000 log.log | grep 'SOME_TEXT' | less ``` Output: ``` random text SOME_TEXT another 1000 chars random SOME_TEXT 2000 chars text text SOME_TEXT 2000 chars ``` But its hard for me to separate them as those are screen full of texts(also not pleasant for eyes either). I want to have my output like blow: ``` random text SOME_TEXT another 1000 chars random SOME_TEXT 2000 chars text text SOME_TEXT 2000 chars ``` And I have modified my above command with `sed`: ``` tail -n 1000 log.log | grep 'SOME_TEXT' | sed 's/\n/\n\n/' | less ``` It didn't work, so I tried with `tr` next: ``` tail -n 1000 log.log | grep 'SOME_TEXT' | tr '\n' '\n\n' | less ``` It didn't work with me either. What am I missing here?
