title: Does tail -f always use inotify?
body: <p>I am using tail -f (on Linux) and am trying to figure out how I should use the -s parameter to set the polling interval. A colleague told me that -s0 would cause tail to use inotify instead of polling but I cannot find that in the documentation for tail.</p>
  
  <p>The binary files I am tailing change constantly - does this suggest I should use -s0 or some fraction of second (like -s0.1) instead?</p>
