RE: Question Re: Piping and Redirection

Hi, Vern:

No, that's correct.  The -f flag tells tail to hang in there until ^C is
pressed.  It's kind of cool, as mentioned, for watching logs.  Imagine a
self-refreshing DSPMSG display, for example, and you might begin to see the
benefit.

Or assume there's a file that logs everytime someone logs in, and you want
to know (or, more to the point, want a program to know) when a particular
user logs in.  Hmmmm....   voila yourself!  :)

Hi Dennis

You don't have to do anything? Does tail automatically refresh? Don't you
have to repeat the command? I assume history can get it for you.

With DSPPFM, all you need to do is leave a 'b' in the control field and
press ENTER. Voila!

Cheers

Vern
