Other useful txt editing commands
Have you ever needed to look at the last entries in a log file.
Of course you have.
For example you want to see the last errors in the /var/logs/mail.log file
If you open it with NANO or some other txt editing programme you will have to scroll all the way to the bottom.
AND if more entries are logged while you are already in the file you will not see them!
This is a pain
