Hi Uri,

Real Unix Men were once little children too, and passed through various 
stages as they
developed their magical powers in dealing with xubuntu or more in 
general unix.
Others, though, became Real Expert Men in other areas, never having had 
the time
or the motivation to learn other OSs than a 1960s IBM system or the cos 
that came
with the Cray7600 in the 1970s. Then, when it came time to learn new 
magic with
linux and xubuntu, they must use a walker in unix land and count on the 
Real Unix Men
to help them cross the street or whatever else might cause difficulty if 
they mess up.

So, my reaction was intended to gently remind the experts that this list 
is lurked
on by all kinds, from experts who contribute to those who want to more 
than to find
glimmers of insight or stimulus to explore a little and learn from it. 
For the latter it is
best not to assume too much knowledge, e.g., an active knowledge of what 
$PATH
is for. Instead, it is more helpful to be explicit in the commands that 
are needed to make
things work even if these are very basic. That's how many people learn, 
by repetition
ad nauseam.

Really helpful is Ulli's correction to where I put the path to the 
fstools-0.0 directory.
When I first did it, I vaguely remembered something about PATH in 
.bashrc. So I looked
where to add to the $PATH variable, and I noticed a reminder to myself 
that it should
be put in .bash_aliases. When I looked there I did find another addition 
to $PATH,
so I added it there. Thanks to Ulli, I realized that I should have put 
it in .profile, so I
did that and added a note to myself reminding me what .bashrc, 
.bash_aliases and .profile
are for. Then I might do it properly when the next time to do this rolls 
along. Maybe 2018...,
or never. but then again who knows.

Trying to learn some more, I tried sudo apt get install sw,
and sudo apt-get install swtools, but nothing useful happend. So I gave 
up, since I
don't really need any of this right now and I have other things to do, 
like listening
to  songs on youtube with my grandchild.

Be this what it may, thanks to Ulli and others who make it worthwhile to 
lurk on xubuntu-users.

Nino
