Once "less" is displaying the output, you can press Shift-f (capital 'f') to have it follow the output. To get it to stop following the output, type Ctrl-c. You can repeat this again and again. The problem I found long ago (which might be fixed by now) is that if I ran "less" in the same bash shell/window as the process I was monitoring (that is, if I ran, say, a build in the background via '&') then this would abort the process. I was able to get around this problem by running "less" in a separate bash shell/window from the process I was monitoring. This bug might have been fixed in a recent Cygwin release, but I haven't checked it. As far as your "tail -f" problem is concerned, I don't know the reason for it or a quick fix, but you might try running "tail -f" in a separate bash shell from the process you are monitoring, just as I do with "less". Or, you might try using "less".
