Let's say we do:
tail -f /var/log/apache2/error.log
Then we see what we want to see, and then, we want to quit, so that we can navigate to other directories and so on... So, the question is:
How can we quit tail ?
I've tried to type: 'q', and 'exit', and 'quit', and 'kill', no luck.
The answer to your query is to hit Ctrl + C together
In Linux Mint 18 the answer actually is q to quit out of a tail view in terminal
