I'd wager that 90% of the time that I'm using 'tail -F' I'm also piping it to grep.

  This. I use: tail -f /var/log/x.log | grep foo -A 20 -B 20 Most of the time.

    You know you can also do -C 40 for 40 lines of context instead of -A 20 -B 20

      Note that -C is in each direction, not total; -C20 is equivalent to -A20 -B20.
