less can be used to replace
tail -f file
to provide features like handling binary output and navigating the scrollback:
less +F file
+ prefix means "pretend I type that after startup", and the key
F starts following.
less also replace
tail --follow=name file
file even if the actual file gets deleted or moved away, like a log file that is moved to
file.log.1, and then a new file is created with the same name as the followed file?
