You can use
less +f instead of everyone's favorite
tail -f when watching a log. This gives you the 'following' behavior of
tail with the buffer navigation features of the
less pager, allowing you to search, scroll, etc.
tail mini pro-tip: if you're following a log file that gets rotated, use
tail -F with a capital 'F' to have tail automatically switch to tailing the new file when it gets rotated.
