I have a file that contains data including urls. But there are various lines which are not urls. How can I remove them using Ubuntu terminal commands?
Here is the Sample file for reference: Sample Data
com.blendtuts/S
°=
com.blengineering.www/:http
±=
I want to have the output :
com.blendtuts/S
com.blengineering.www/:http
The extra unwanted lines do not have any dot. Hence, I want to remove the lines without dots
